Hardell: si arriva ad un maggiore rischio del 300% per uso celllulare e cordless per più di 25 anni

Altro recentissimo lavoro pubblicato dal team del Prof Hardell su uno studio epidemiologico su oltre 5000 persone, di cui 1500 con diagnosticato tumore al cervello.

il rischio di glioma si incrementa  del +30% nel caso  di uso di cellulare e cordless da più di un anno fino a ben il 300% quando l'uso è prolungato per più di 25 anni.

Il rischio raddoppia per un uso cumulativo di 1500 ore ... che vuol dire pari a 30' al giorno per 8 anni ! Notare bene ...  
Ricordo che uno studio sui consumi di (solo) telefono cellulare, americano datato forse 2010 (?) indicava che l'utilizzo medio degli utenti era di mezz'ora al giorno !   E in un periodo antecedente l'esplosione degli smartphone , del 4G, etc.   
Quindi una grande fetta degli utenti è a fortissimo rischio ,e  non solo i grandi utilizzatori come i media ufficiali ci aveva informato dopo il progetto Interphone.

Cell and cordless phone risk for glioma - Analysis of pooled case-control studies in Sweden, 1997-2003 and 2007-2009

L. Hardell, M. Carlberg, Cell and cordless phone risk for glioma - Analysis of pooled case-control studies in Sweden, 1997-2003 and 2007-2009, Pathophysiology (2014), Available online 29 October 2014. http://dx.doi.org/10.1016/j.pathophys.2014.10.001

Abstract


We made a pooled analysis of 2 case-control studies on malignant brain tumours with patients diagnosed during 1997-2003 and 2007-2009. They were aged 20-80 years and 18-75 years, respectively, at the time of diagnosis. Only cases with histopathological verification of the tumour were included. Population-based controls, matched on age and gender, were used. Exposures were assessed by questionnaire. The whole reference group was used in the unconditional regression analysis adjusted for gender, age, year of diagnosis and socio-economic index.

In total 1,498 (89%) cases and 3,530 (87%) controls participated. Mobile phone use increased the risk of glioma, OR = 1.3, 95% CI = 1.1-1.6 overall, increasing to OR = 3.0, 95% CI = 1.7-5.2 in the > 25 year latency group. Use of cordless phones increased the risk to OR = 1.4, 95% CI = 1.1-1.7, with highest risk in the >15-20 year latency group yielding OR = 1.7, 95% CI = 1.1-2.5. The OR increased statistically significant both per 100 h of cumulative use, and per year of latency for mobile and cordless phone use. Highest ORs overall were found for ipsilateral mobile or cordless phone use, OR = 1.8, 95% CI = 1.4-2.2 and OR = 1.7, 95% CI = 1.3-2.1, respectively. The highest risk was found for glioma in the temporal lobe. First use of mobile or cordless phone before the age of 20 gave higher OR for glioma than in later age groups.

Key Findings

The relative risk of glioma for wireless (cell and cordless) phone use increased from 1.3 (95% CI = 1.1-1.6) for more than 1 year of use to 3.0 (95% CI = 1.7-5.2) for more than 25 years of use (Table 2).
The ipsilateral (same side of head where phone was used) relative risk of gloma for cell phone use increased from 1.8 (95% CI = 1.4-2.2) for more than 1 year of use to 4.6 (95% CI = 2.1-10.0) for more than 25 years of use (Table 5).

The contralateral (opposite side of head where phone was used) relative risk of gloma for cell phone use increased from 1.1 (95% CI = 0.8-1.4) for more than 1 year of use to 3.2 (95% CI = 1.2-8.6) for more than 25 years of use (Table 5).
The overall relative risk of glioma for 1-122 hours of wireless phone use was 1.2 (95% CI = 0.9-1.4) whereas the risk for more than 1,486 hours was 2.0 (95% CI = 1.6-2.6) (Table 6).
The ipsilateral relative risk of glioma for people who first used mobile phones  at less than 20 years of age was 2.3 (95% CI =1.3-4.2) whereas the risk for those who first used mobile phones at 50 years of age or older was 1.7 (95% CI =1.3-2.2) (Table 8).


Excerpts

Detailed information on materials and methods has been given previously ...For 1997-2003, cases and controls covered central Sweden [13], whereas the 2007-2009 study included the whole country [24] ...

Controls were ascertained from the Swedish Population Registry, covering the whole country and being continuously updated, such that each person was traced by a unique ID number. The registry also records the address to each person. For each case, one control subject of the same gender in the same 5-year group was drawn at random from this registry. They were assigned the same year for cut-off of all exposure as the diagnosis of the each case ...

Exposure was assessed using a mailed questionnaire sent to each person. Regarding use of a mobile phone, the time of average use (min per day) was estimated. The technology has changed since the first introduction of mobile phones. The first generation was analogue phones with an output power of 1 W at about 900 MHz followed by the 2nd generation GSM phones (2G) with either 900 or 1800 MHz frequency and with a pulsed output power. The mean output power was of the order of tens of mW. In the 3rd generation phones (3G) the output is more to be characterized as amplitude modulated than pulsed and the output power is of the order of tens of μW ...

Some special questions covered the extent of use in a car with an external antenna, and use of a hands-free device, both regarded as non- exposure to RF-EMF. The ear mostly used during phone calls, or equally both ears, was also noted.

Use of cordless desktop phones was covered by similar questions; years, average daily use, use of a hands-free device, and preferred ear. The procedure was conducted without knowledge of case/control status. Use of the wireless phone was referred to as ipsilateral (>50% of the time) or contralateral (<50% of the time) in relation to tumour side....

The questionnaire also contained a number of questions relating to the overall working history, exposure to different chemicals and other agents, smoking habits, X-ray investigations of the head and neck, and heredity traits for cancer ...

Adjustment was made for the matching variables gender, age (as a continuous variable) and year of diagnosis. It was also made for socio-economic index (SEI) divided into 4 categories ...

In total, 1,691 cases fulfilling the inclusion criteria were enrolled. Of these cases, 1,498 (89%) answered the questionnaire, of whom 879 were men and 619 women. The mean age was 52 (median 54, range 18-80) ...

Of the 4,038 controls, 3,530 (87%) participated, 1,492 men and 2,038 women. The mean age was 54 (median 55, range 19-80) ...

The median latency time for use of mobile phones in glioma cases was 9.0 years (mean 10.1, range 2-28). The corresponding results for cordless phones were median 7.0 years (mean 8.0, range 2-21) ... Analogue phones gave OR = 1.6, 95% CI = 1.2-2.0, increasing to OR = 4.8, 95% CI = 2.5-9.1 in the latency group of
>25 years. Note that the latency time was counted from the first use of the specific telephone type; for instance, a 2G digital phone user may have previously used an analogue phone.

Use of digital 2G phones gave overall OR = 1.3, 95% CI = 1.1-1.6 increasing to OR = 2.1, 95% CI = 1.5-3.0 with a latency >15-20 years, the longest latency interval. The results for digital 3G phones showed highest risk in the >5-10 years latency group, OR = 4.1, 95% CI = 1.3-12 ...

Digital type of mobile phones (2G, 3G) gave in total OR = 1.3, 95% CI = 1.1-1.6, increasing to OR = 2.1, 95% CI =1.5-3.0 in the longest latency group (>15-20 years).

Use of cordless phones gave OR = 1.4, 95% CI = 1.1-1.7, with highest risk in the latency group >15-20 years, OR = 1.7, 95% CI = 1.1-2.5 ...
The digital type of wireless phones (2G, 3G and/or cordless phone) gave OR = 1.3, 95% CI = 1.1-1.6, increasing to OR = 1.6, 95% CI = 1.3-2.0 in the latency group >5-10 years, then tending to drop, and again increasing to OR = 2.0, 95% CI = 1.5-2.8 risk in the latency group >15-20 years.

The group of total wireless phone use (mobile phone and/or cordless phone) gave similar results to mobile phone use, with increasing risk with latency yielding highest risk in the longest latency group >25 years; OR = 3.0, 95% CI =1.7-5.2.

The risk increased per additional year of latency given for wireless phones; OR = 1.032, 95% CI = 1.019-1.046 ...

Wireless phone total use (>1,486 h) gave OR = 2.0, 95% CI = 1.6-2.6 in the 4th quartile, with similar results for total mobile and cordless phone use.

ORs increased statistically significant per 100 h of cumulative use for all types of phones (Table 3). Wireless phone increased the risk OR = 1.011, 95% CI = 1.008-1.014 per 100 h of cumulative use ...

The risks of glioma, based on different age groups for first use of wireless phones, are given in Table 8. Regarding mobile phone use, the highest OR was obtained for first use before the age of 20 years, OR = 1.8, 95% CI = 1.2-2.8. The risk increased for ipsilateral use to OR = 2.3, 95% CI = 1.3-4.2. Cordless phone gave OR = 2.3, 95% CI = 1.4-3.9 in total for the age group < 20 years, increasing to OR = 3.1, 95% CI = 1.6-6.3 for ipsilateral use.

Most of the types of malignant brain tumours were glioma (n = 1,380, 92.1%). The most malignant variety, astrocytoma grade IV (glioblastoma multiforme)
constituted 50.3% of the gliomas ... This study clearly shows an increased risk for glioma associated with use of both mobile and cordless phones, a risk that increased significantly with latency and cumulative use. The highest risk was in the longest latency group (> 25 years), giving a statistically significant 3-fold increased risk. Overall a high risk was found for use of the third generation (3G) mobile phones, with OR=4.1, 95% CI = 1.3-12 in the latency group >5-10 years. The risk increased with 4.7% per 100 h cumulative use and with 15.7% per year of latency.

Children and adolescents are more exposed to RF-EMF than adults due to thinner skull bone, higher conductivity in the brain tissue, and a smaller head. Also the developing brain is more vulnerable than in adults and it is still developing until about 20 years of age [31]. We analysed glioma risk in different age groups for first use of a wireless phone. Regarding both mobile and cordless phones OR was highest among subjects with first use before 20 years of age. The risk increased further for ipsilateral use to OR = 2.3, 95% CI = 1.3-4.2 for mobile phone use and to OR = 3.1, 95% CI = 1.6-6.3 for cordless phone use. These results are
consistent with our previous findings [8,15,29,30].

One strength of our study was the high percentage of participating cases and controls, 86% and 87%, respectively, making it unlikely that selection bias influenced the results ...

Recall bias might have been an issue, such that cases would have overestimated their use of  wireless phones. To address this point, we used meningioma cases from the same study as the reference entity in one analysis, which showed an increased risk of glioma with wireless phone use. Thus it is unlikely that our present results using population-based controls are explained by recall bias.
Of certain interest is the higher risk we observed for 3G mobile phone use compared with other types. However, this observation was based on short latency and rather low numbers of exposed subjects. Contrary to 2G GSM, 3G universal global telecommunications system (UMTS) mobile phones emit wide-band microwave (MW) signals. Hypothetically, UMTS MWs may result in higher biological effects compared to GSM signal because of eventual "effective" frequencies within the wideband [32,33]. To our knowledge, there are only two mechanistic studies, which compare effects of 2G and 3G signals using the same experimental approach under well-defined conditions of exposure [32,34] ...

In analysis of survival of glioma cases in our previous studies [13,15,25], we found generally a decreased survival of glioma cases with long-term and high cumulative use of wireless phones [36]; this indicates a complex biological effect from RF-EMF exposure and strengthens a causal association between glioma and the use of wireless phones.

Conclusion. We previously analysed the evidence on glioma associated with the use of  wireless phones using the Hill criteria [20]. We concluded that glioma and also acoustic neuroma are caused by RF-EMF emissions from wireless phones, and thus regarded as carcinogenic, under Group 1 according to the IARC classification, indicating that current guidelines for exposure should be urgently revised. This pooled analysis gives further support to that conclusion regarding glioma.

I casi di tumore al cervello in Svezia sono aumentati o no ?


Ancora una volta si raccontano verità ... relative e non assolute.

Mentre da una parte

Joachim Schüz, a senior manager at IARC, is one of those who points to stable cancer rates as an indicator that cell phones are safe (see “IARC Tries To Play Down Cell Phone Tumor Risks”). Schüz was previously with the Danish Cancer Society and is a coauthor of the Danish cohort study that shows no increased cell phone–tumor risks.

ovvero si dice che non c'è un  incremento del numero di tumori al cervello mentre c'è stato un forte incremento nello uso del cellulare,
dall'altra andando a scavare sui numeri si vede che (Swedish National Board of Health (Socialstyrelsen):

Diagnosis2003200420052006200720082009201020112012
C71 Malignant tumor in the brain1 3401 3391 3881 4341 3921 4251 4341 4571 4421 403
D43 Tumor of unknown nature in brain/CNS7237557817637747548868841 016968

... che effettivamente il numero totale non aumenta mentre aumenta notevolmente il numero di tumori al cervello di natura sconosciuta dai settecento ai mille !

Quale è la verità ? !

WallStreetJournal: molte antenne violano la sicurezza dei lavoratori contro le RF


Articolo sul Wall Street Journal 

Many Sites Violate Rules Aimed at Protecting Workers From Excessive Radio-Frequency Radiation

Uno su 10 siti viola le norme di sicurezza per i lavoratori che accedono ai tetti, solai etc..  Questo è il risultato di un controllo di oltre 5000 siti !
L'ente preposto al controllo , FCC, non ha le risorse per eseguir questi controlli ...!




The antennas fueling the nation's cellphone boom are challenging federal safety rules that were put in place when signals largely radiated from remote towers off-limits to the public.
Now, antennas are in more than 300,000 locations—rooftops, parks, stadiums—nearly double the number of 10 years ago, according to the industry trade group CTIA.
Federal rules require carriers to use barricades, signs and training to protect people from excessive radio-frequency radiation, the waves of electric and magnetic power that carry signals. The power isn't considered harmful by the time it reaches the street, but it can be a risk for workers and residents standing directly in front of an antenna.
One in 10 sites violates the rules, according to six engineers who examined more than 5,000 sites during safety audits for carriers and local municipalities, underscoring a safety lapse in the network that makes cellphones hum, at a time when the health effects of antennas are being debated world-wide.
The FCC has issued just two citations to cell carriers since adopting the rules in 1996. The FCC says it lacks resources to monitor each antenna.
"It's like having a speed limit and no police," said Marvin Wessel, an engineer who has audited more than 3,000 sites and found one in 10 out of compliance.
On a sweltering June day in Phoenix, Mr. Wessel strolled through a residential area near Echo Canyon Park and spotted lawn chairs near a T-Mobile US Inc.  cellular antenna painted brown to match a fence. His monitor showed emissions well above safety limits.
After being alerted by The Wall Street Journal, T-Mobile added warning signs and roped off a patch in front of the antenna with a chain. "The safety of the public, our customers and our employees is a responsibility that all of us here at T-Mobile take very seriously," said a T-Mobile spokeswoman.
At very high levels, radio-frequency radiation can cook human tissue, the FCC said, potentially causing cataracts and temporary sterility and other health issues.
To buffer people from these "thermal" effects, the FCC set two limits for how much RF people can absorb—one for the general public, and an "occupational" limit five times higher for people trained to work near antennas. The higher level is still 10 times below the thermal level.
Carriers have to restrict access near antennas that are above the limits. Workers and others who venture into hot zones—generally up to 20 feet in front of an antenna—must be trained and have RF monitors.
Most cellular antennas aren't strong enough to cause thermal problems, engineers say, and carriers are installing some smaller antennas with lower power levels. But some are being made stronger to meet demand for high-speed Internet access, high-definition video and other services. A German study in 2013 found higher emissions from 4G antennas.
"The more bandwidth, the hotter they will be," said Mr. Wessel, who expects some to exceed the thermal level within a year.
Richard Tell, a Nevada engineer, also expects some emissions to rise. At more than 1,000 sites nationally, he found roughly one in 10 out of compliance, similar to Mr. Wessel's conclusion. Some are hidden or disguised for aesthetic reasons.
"I've been on rooftops looking for antennas and couldn't find them because they were hidden in fake concrete blocks that were really foam," he said.
Daniel Ranahan, a Lowell, Mass., roofer, said antennas are slowing jobs. "There's no mechanism for the worker to know what buildings are safe," he said.
Peter Chaney, the director of safety and health for the Mechanical Contractors Association of America, which represents companies with more than 270,000 workers, in August asked the FCC to create a database of cellular antennas.
One company, RF Check, in San Diego, has designed a protocol but requires collaboration from carriers and funding from phone customers.
Mr. Chaney is developing a training video and brochure on RF safety to distribute to the association's members next year.
"We want workers to know that the antennas are there and that there may be a potential hazard," he said. "I'm concerned about the chronic effect of this. If guys have 30-year careers and they're exposed to these things on a regular basis—is there any long-term effect?"
The National Institute for Occupational Safety and Health began studying that question after the World Health Organization in 2011 categorized RF radiation as a possible carcinogen, based on research by over 30 scientists, said Gregory Lotz, the top RF expert for Niosh. And the National Toxicology Program at the National Institutes of Health is exploring lower-level RF exposure.
An FCC guideline written after the rules were adopted notes studies showing "relatively low levels" of RF radiation can cause "certain changes in the immune system, neurological effects, behavioral effects," and other health issues, including cancer. "Results to date have been inconclusive," however, the agency said in a guide to radio-frequency radiation, and need to be studied further.
Among those concerned is Gilbert Amelio, a scientist who was chief executive of AppleInc. and National Semiconductor and a board member of AT&T Inc.He believes industry leaders will "take whatever steps may be necessary to prevent harm to workers or others who may have good reason to be close to these sites."
Jimmy Crespo complained to federal labor regulators in 2011 that he became disabled with cognitive issues after working more than 300 times on heating and cooling systems for antennas for Johnson Controls Inc., a Sprint Corp. contractor.
"I had no training, no monitoring devices and no warning from my employer," Mr. Crespo said.
Regulators asked Johnson to ensure the rules were being followed. Johnson said it no longer had the contract, and Sprint said the systems were a safe distance from antennas.
"Employees were not working in an area where radio frequencies would pose a hazard," a Johnson spokesman said.
Sprint said annual checks show all sites are compliant.
AT&T said it places "the utmost importance on the safety of workers and the public from RF emissions and we have a rigorous safety program in place to minimize exposure to RF emissions."
The FCC in April signed a consent decree with Verizon Communications Inc. to settle RF violations in Pennsylvania and Connecticut, involving an unlocked rooftop and a missing sign. Verizon agreed to pay $50,000 and to train employees and contractors, and check other sites.
The carrier has told regulators that property owners complicate compliance.
"In New York City, condominium tenants became upset and concerned with RF notification signs we placed on a terrace access point," Tamara Preiss, Verizon's vice president of federal regulatory affairs, wrote to the FCC in February. Ms. Preiss said the signs were removed after the tenants hired a lawyer.
Insurers are becoming concerned. "The risk is often transferred to 'unsuspecting' property owners," Roger Egan, executive chairman of Risk Strategies Co., told the FCC.
Hartford Financial Services Group Inc.  and A.M. Best Co., the insurance-rating agency, have flagged RF as an emerging risk. Swiss Re  wrote in a 2013 report that if RF radiation is linked to health problems it "could ultimately lead to large losses."

A Volturino _FG le emissioni superano sempre i limiti


Comunicato stampa


Impianti radiotrasmittenti a Volturino, Gagliardi: "Costante superamento dei limiti"


Prosegue la battaglia del presidente dell'associazione elettrosmog Volturino, Antonio Gagliardi: "L'Associazione reitera la richiesta di incaricare ispettori per un sopralluogo obiettivo del c.e.m"

Comunicato -  

Avatar di AntonioInserito da Antonio 3 ottobre 2014
Sembra non abbiano prodotto alcuno stimolo le comunicazioni dell'associazione del 28 aprile, 11 giugno e 21 luglio, segnalanti il superamento dei limiti legali delle emissioni elettromagnetiche propagate dagl'impianti radiotrasmittenti situati a ridosso degli ambienti privati del comune di Volturino.
Le emissioni, controllate periodicamente dall'associazione, continuano a superare il limite dei 20 V/m nell'area degl'impianti e dei 6 V/m, sino ad arrivare a oltre 9 V/m, sui balconi degli abitanti esposti più direttamente alle antenne, mentre la parte opposta del paese sembra appartenere ad un altro comune, circa 1 V/m di c.e. rilevato.
Più preoccupante è la rilevazione scaturita sui letti di alcuni sfortunati insonni che ha registrato valori sino a 3,3 V/m, valori legali certo, ma non certo scientifici. E' così che si persegue "al massimo grado" l'obiettivo di minimizzare e di rendere uniforme sul territorio l'esposizione della popolazione? Anche la Carta Costituzionale è imperativa nel suo articolo 3 "Tutti i cittadini hanno pari dignità sociale e sono eguali davanti alla legge"
O forse è più importante rassegnarsi agl'interessi economici degli anarchici abusivi che oltretutto non hanno titoli neanche per emissioni di 0,1 V/m, essendo molti operatori sprovvisti di concessione ministeriale e comunale. L'Associazione reitera la richiesta di incaricare ispettori per un sopralluogo obiettivo del c.e.m. che ponga fine alle ipocrite risultanze dell'Arpa che fanno da scudo al piano di risanamento o di trasferimento in altro sito e di tenere informato il sottoscritto presidente.
