The BlocSock is a small, 3”x5½”, lightweight case that's only designed for cell phones, not tablets or laptops. One side is a normal fabric to ensure reception. The other side has a rectangular, metallic mesh to shield RF radiation. It's recommended that you keep the side with the shielding material between the phone and your body. When making or receiving calls, keep the shielding between your head and the phone. It can also be moved into a smaller “kangaroo style” pouch during calls. It's effective, and tests show that it reduces RF exposure 96%. For more information, check out the SAR research test or watch this video.

The authors of these studies noted that the results were preliminary and that possible health outcomes from changes in glucose metabolism in humans were unknown. Such inconsistent findings are not uncommon in experimental studies of the biological effects of radiofrequency electromagnetic radiation in people (4). Some factors that can contribute to inconsistencies across such studies include assumptions used to estimate doses, failure to consider temperature effects, and lack of blinding of investigators to exposure status.

Another animal study, in which rats were exposed 7 days per week for 19 hours per day to radiofrequency radiation at 0.001, 0.03, and 0.1 watts per kilogram of body weight was reported by investigators at the Italian Ramazzini Institute (35). Among the rats with the highest exposure levels, the researchers noted an increase in heart schwannomas in male rats and non-malignant Schwann cell growth in the heart in male and female rats. However, key details necessary for interpretation of the results were missing: exposure methods, other standard operating procedures, and nutritional/feeding aspects. The gaps in the report from the study raise questions that have not been resolved.
According to Dr. Devra Davis, who wrote Disconnect: The Truth About Cell Phone Radiation, cell phones are dangerous because they emit erratic signals capable of disrupting resonance and DNA repair. As long as your cellular phone is on, it sends out radiation intermittently. Even if you don’t take your phone out of your pocket all day, it continues to expose you to radiation. Dr. Joseph Mercola, founder of Mercola.com recently wrote an excellent article on the dangers of cell phones and provided common sense ways we can protect ourselves and our family from the electromagnetic radiation it emits.

So you are careful about NOT putting your radiation emitting mobile near your head. That’s good. But think about this: what body parts get the radiation when you put the thing on your pocket, bra, hat, purse, holster or elsewhere on your body? Now your vital and sometimes private organs are basically in contact with the source of the microwaves, getting the largest dose possible. Pocket Sticker is a high performance shielding patch that you stick onto your clothing which reflects that radiation away from your body.
In June, at a meeting of scientific counselors to the toxicology agency, Donald Stump, one of the members, worried that the study “will be vulnerable to criticism that it was conducted using outdated technology.” The challenge, he added, is how to move forward with experiments that are large enough to be significant yet nimble enough to keep pace with the rapidly evolving devices.
In addition, cellphones potentially harm our health in ways that have nothing to do with cancer. The effect on sperm is concerning to Moskowitz, the director of the Center for Family and Community Health at the Berkeley School of Public Health, and he noted that our current cellphone regulations also don’t account for these potential effects. Plus, we still don’t know what steady exposure to this kind of radiation from devices means for kids.
INTEGRITY: Many manufactures claim near 100% EMF protection, referring to the radiation blocking material, NOT the protection you receive on a call. If you covered your whole phone with EMF blocking material, then you'd have no signal. Our EMF blocking material is used on the front cover only, providing you real EMF protection with no sacrifice in reception.
If you're concerned that talking on your cell phone could cook your brain, you may want to invest in an anti-radiation phone case. The basic idea behind these cases is that they redirect the radiation produced by the phone away from the user, so it isn't constantly bombarding your skull. They can accomplish this in a variety of ways; one involves using antennas to redirect the waves, and another uses silicone or other materials to block the waves.
Mobile phone use and the development of tumors in the exposure area. Accordingly, Dr. Elisabeth Cardis from the International Agency for Research on Cancer - IARC, started organizing a study (the INTERPHONE) with the participation of 16 sites worldwide, in the purpose of assessing whether use of mobile phones is connected with an increased risk for developing brain tumors (benign and malignant), auditory nerve tumor and salivary gland tumors. The purpose of the cooperation was to reach a satisfactory sample size that could answer the question from the statistical aspect and also to establish a situation where the study represents enough subjects who have used the mobile phone over a relatively long period (at least 10 years). In Israel, the study was conducted by Dr. Siegal Sadetzki, Director of the Cancer Epidemiology and Radiation Unit at the Gertner Institute, Sheba Hospital.
Want to let people know that cellphones cannot be used in certain areas without an embarrassing confrontation? These decals are suitable for putting up in schools, restaurants, theaters, stores, taxicabs, busses, trains, hospitals, offices, homes or any other place that's appropriate for a cellphone-free zone. High quality decals measure 3½" by 3½". Nice strong adhesive, simply peel and stick.
Overall, the reviews of case-control studies seem to suggest there is perhaps no risk of cancer with cellphone use — unless you look at some subgroups (like people in blinded studies or people with long-term exposures). But these reviews are based on case-control studies — which are like the National Enquirer of the science world: cheap and often misleading.

Can cellphone radiation cause cancer in humans? There’s no scientific consensus on this issue, but there is “some evidence” that exposure to radiation equivalent to that emanating from 1990s-era cellphones is associated with brain tumors in male rats, according to results of a US National Toxicology Program (NTP) study released last week (November 1). 


The NTP studied radiofrequency radiation (2G and 3G frequencies) in rats and mice (33, 34). This large project was conducted in highly specialized labs that specified and controlled sources of radiation and measured their effects. The rodents experienced whole-body exposures of 3, 6, or 9 watts per kilogram of body weight for 5 or 7 days per week for 18 hours per day in cycles of 10 minutes on, 10 minutes off. A research overview of the rodent studies, with links to the peer-review summary, is available on NTP website. The primary outcomes observed were a small number of cancers of Schwann cells in the heart and non-cancerous changes (hyperplasia) in the same tissues for male rats, but not female rats, nor in mice overall.
EWG also reviewed data in the FCC filings on tests of battery life during a continuous call, measured on an iPhone 4 without a case and on the same phone with an Incipio Le Deux case. This case was chosen because it contains metallic parts (a stainless steel back plate). The presence of metallic components influences the phone’s radiation properties, as the FCC acknowledges (FCC 2001; FCC 2014). Under the test conditions with constant signal strength, an iPhone 4 without a case had 85 percent of battery capacity after a one-hour call and 70 percent after two hours. When the test was repeated with the Incipio Le Deux case, the phone had only 65 percent of battery capacity after a one-hour call and only 10 percent after two hours (Pong 2012).
They determined there is “clear evidence” that male rats exposed to high levels of radio frequency radiation — typical of 2G and 3G networks when the study was designed — developed heart schwannomas. There was also “some evidence” of brain and adrenal gland tumors, again in the male rats, but the exposed female rats, and male and female mice, did not have consistent patterns of disease.
So you are careful about NOT putting your radiation emitting mobile near your head. That’s good. But think about this: what body parts get the radiation when you put the thing on your pocket, bra, hat, purse, holster or elsewhere on your body? Now your vital and sometimes private organs are basically in contact with the source of the microwaves, getting the largest dose possible.

We purchased a cell phone case directly from SafeSleeve. Once received, we attempted to determine how much radiation protection is actually possible from the product. What we learned is that NONE of the products SafeSleeve sells are actually tested by an FCC approved lab. Their advertising is very misleading! The testing results they use as "proof" that their products are tested was a single test done ONLY on a piece of material they claim is used inside their products. NONE OF THEIR PRODUCTS HAVE EVER BEEN TESTED BY AN FCC APPROVED TESTING LAB. We read the test report from SafeSleeve's website and called the testing lab listed on the report who verified this information. We also called an independent, FCC approved cell phone testing lab and they explained the same thing. We were informed that radiation comes from all sides and edges of a cell phone, so when you use the SafeSleeve cell phone case, you are NOT being protected. SafeSleeve cell phone cases offer you no more protection than using a cell phone without a case. To protect yourself from cell phone radiation, you still need to use hold the phone at least 6-8 inches from your body, use the speaker for conversations, text more than talk, and don't use or carry your cell phone against your body. We attempted to have the SafeSleeve cell phone case tested and were informed that to have it properly tested would require paying thousands of dollars in a lab equipped for such testing; using an RF meter or similar device to test a cell phone case will not provide meaningful or accurate results. If SafeSleeve were an honest company, they would have each of their products tested in an FCC approved lab, the same type of lab that cell phones are tested in. However, SafeSleeve is not willing to spend the money. If you don't believe us, call an FCC approved cell phone testing lab and ask a few questions. In the meantime, don't waste your money on SafeSleeve products. Note: SafeSleeve attempts to protect themselves by not listing any business phone number or business address on their website. Any questions/complaints you may have with SafeSleeve are strictly handled via email. They refused our request to speak to a "real person" regarding our questions or issues with their products. Does the word SCAM apply here? We think so.
I noticed the Blocsock hardly added any bulk to my phone, and fit comfortably in my pocket. I have a Rocketfish RF-MTVT2SP protective gel case and thankfully the phone fits the Blocsock without having to take off this case. The Blocsock is very easy to use, and is quick and easy to take out and answer the phone. Again, if you get one, make sure the size you order is right and not too tight or loose. The pouch on the Blocsock is handy when using the phone to call people so the phone can be placed in the pouch between the Blocsock and me, protecting my head from radiation while still enabling people to clearly hear me and vice versa.
What the study showed: Self-reported cell phone use was not associated with an increased risk of glioma, meningioma, or non-central nervous system tumors. Although the original published findings reported an association with an increased risk of acoustic neuroma (14), this association disappeared after additional years of follow-up of the cohort (15).
