Another way to think about the situation is to consider the steady state power emission of .02 Watts and ask how long it would take to heat up your body by one degree Celsius if your entire volume was exposed. Take your body mass to be 100 kg and approximate it as being composed entirely of entirely of water. If all of the radiation was absorbed and went into heating you up (which it isn’t), it would take 20900000 seconds (specific heat*mass*1 degree/power) or 241 days to heat you up by one degree. Fortunately, you have metabolic processes in your body, or possibly air conditioning, to mitigate this heating.
Users were defined as anyone who made at least one phone call per week for six months between 1982 and 1995. So any person who made 26 calls was a cell phone user and therefore considered exposed to radiation. Those with less than 26 calls were non-users. In reality, the radiation exposure between users and non-users defined in this manner is not discernable.
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.
The tricky part about measuring the radiation from a cell phone is that the emission strength varies widely over time. There will be strong bursts of varying intensity, followed by quiet periods. This makes it hard to compare "apples to apples". Also, because you are measuring up close to the source, you must use a near field meter AND you must maintain the position of the meter very precisely.
None of the three cases contain metallic parts, which are known to affect SAR, but all increased the user’s radiation exposure. The effect on radiation exposure would likely vary with each of the hundreds of cases on the market, and each would have to be tested individually to come up with an exact measure. The results in Table 1, however, are believed to reflect the range of radiation increases.
In one type of study, called a case–control study, cell phone use is compared between people with these types of tumors and people without them. In another type of study, called a cohort study, a large group of people who do not have cancer at study entry is followed over time and the rate of these tumors in people who did and didn’t use cell phones is compared. Cancer incidence data can also be analyzed over time to see if the rates of brain tumors changed in large populations during the time that cell phone use increased dramatically. These studies have not shown clear evidence of a relationship between cell phone use and cancer. However, researchers have reported some statistically significant associations for certain subgroups of people.
In fact, nobody can really explain how exactly cellphone radiation could cause cancer, says Christopher Labos, a cardiologist and biostatistician at McGill University. “You don’t necessarily have to understand how something works to prove that it’s dangerous, but it would certainly make the case more compelling,” says Labos, who wrote a detailed analysis for Science-Based Medicine about the recent government cellphone radiation study.
SafeSleeve's report is right up front about showing that they do not test or certify the Safe Sleeve case, rather they are simply testing the material they put into the case in a completely artificial environment, in a laboratory setting, using a signal generator and a power amplifier. Safe Sleeve includes photos showing how the measurements are taken. But that may not be how anyone will ever use their phone.
We spent 45 hours on research, videography, and editing, to review the top choices for this wiki. Sure, there may not currently be any hard proof that cell phones release enough radiation to be harmful, but do you really want to take the chance when you can easily block almost all emissions from reaching your body with one of these anti-radiation phone cases? Most look just as stylish as traditional cases, and some even double as anti-spying and RFID blockers. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best anti-radiation phone case on Amazon.
As in the NTP study, Ramazzini investigators detected statistically elevated rates of heart schwannomas in male rats at the highest dose. They also had weaker findings linking RF exposure to cancer of glial cells in the brain, which were limited to females. Ronald Melnick, a retired NTP toxicologist who designed the NTP study, says a measure of consistency between the two studies is important, because “reproducibility in science increases our confidence in the observed results.”
Forward your cell phone to landlines whenever you are at home, then power off the cell phone without missing a call. Biological effects can be related to both strength of cell phone radiation dose and duration of exposure, so consider whether or not your communication is urgent. Remember: Use a corded home landline (not a home cordless phone, because cordless phones use electromagnetic microwave technology just like cell phones). Most cordless phone base stations constantly emit microwave radiation regardless whether or not any connected handset is in use. The cordless phone handsets also emit microwave radiation. Corded landlines have no radiation emissions and are the best choice.
Independently tested DefenderShield® technology uses a patent-pending sophisticated layering of separate non-toxic, human safe exotic materials processed for maximum radiation blocking efficiency. Each material has unique and targeted radiation shielding characteristics designed to work in unison to up to eliminate all radiation emissions from 0 to 10 GHz.
Affirming research conducted back in the 1970s that brought to light some of the dangers associated with EMFs, scientists from the Environmental Protection Agency (EPA) more recently warned that ELF radiation alters calcium ion activity in cells, which regulates energy production, membrane function and integrity, and both central and peripheral nervous system health.
3. A lab setting is the only legitimate way to show the effectiveness of our technology for a few main reasons: one, a controlled source is the only way to conduct a scientific study. Note that the controlled source that we used was specifically designed to simulate emissions from wireless electronics (RF and ELF emissions of various frequencies). Two, ambient levels in a non-controlled environment will affect readings, rendering the results inaccurate. Three, at-home equipment such as the meter used in the video is not suitable for the types of emissions by a wireless device, nor are they reliable.

The Ministry of Health Medical Administration circular (from 2002) addressed to hospital Directors, states that use of mobile phones and wireless handheld transceivers (walkie talkie) in the hospital, must on the one hand guarantee the patient’s wellbeing and safety, and on the other hand, allow the staff, the patients and their families to enjoy the service benefits. This circular outlines the areas where use of mobile phones is strictly forbidden and areas where use is permitted (while keeping an appropriate safety distance from areas where life-supporting equipment or systems are operated).
Mobile phones emit radiofrequency energy, a form of non-ionizing electromagnetic radiation, which can be absorbed by tissues close to the phone. The amount of radiofrequency energy a mobile phone user is exposed depend on many factors as the technology of the phone, the distance between the phone and the user, the extent and type of mobile phone use and the user’s distance from cell phone towers.

Epidemiology studies investigating cell phone use patterns with human cancer risk have produced inconsistent results. Some studies enrolled people who already had tumors with suspected links to RF radiation, such as gliomas, acoustic neuromas and salivary gland tumors. Researchers compared the self-reported cell phone use habits of the cancer patients with those of other people who did not have the same diseases. Other studies enrolled people while they were still healthy, and then followed them over time to see if new cancer diagnoses tracked with how they used cell phones. All the epidemiology studies, however, have troubling limitations, including that enrolled subjects often do not report their cell phone use habits accurately on questionnaires.
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).
