Also of note, in a study by Henrietta Nittby et al (2009), the lowest exposure SARs were worse than the higher SAR exposures. Some scientists consider blood brain barrier effects at these very low levels of radiation exposure (i.e. 30-45x lower than the ‘Top 10’ lowest SAR phones ranked by the Environmental Working Group) to be of equal or even greater concern for the population than the increase in brain tumors from cell phone use that is expected.
In the spirit of adventure, I tried the snazzy TwelveSouth case pictured in this post, and I admit, there were some things I liked. I got very used to not carrying around a bulk in my back pocket. I even put my keycard for the office in it, and it felt very futuristic to unlock the office door by holding my phone up to the fob sensor. But in the end, I took the case off before a trip. It just seemed too foolish to risk losing everything at once.

In 2015, scientists from around the world united for the International EMF Scientist Appeal based on the results of over 2,000 research papers. The appeal is the collective voice of 190 scientists from 39 different countries. They are calling for tighter regulations and more security measures when dealing with electromagnetic field exposures generally, and WiFi in particular.
“Without following these instructions, we risk being exposed to levels of radiation that are too high- higher than radiation limits set by our federal government. The reality is that radiation emissions from devices are tested before going on the market- with a space between the device and your body. For cell phones the distance varies depending on the manufacturer and is under an inch.” Cell Phone Radiation FAQ’s, Environmental Health Trust; Twitter: @saferphones
Five properties of non-thermal EMF effects are discussed. These are that pulsed EMFs are, in most cases, more active than are non-pulsed EMFs; artificial EMFs are polarized and such polarized EMFs are much more active than non-polarized EMFs; dose-response curves are non-linear and non-monotone; EMF effects are often cumulative; and EMFs may impact young people more than adults.
Say someone found a potential association between carrying coins in your pocket and the risk of a particular type of tumor. It would set off a frenzy of activity among a group of people who were convinced that this association was real. They would lobby for a law requiring that warning signs be placed on change machines. The effect would snowball until some people would demand that the government stop minting coins.

Cancer is the obvious start. An early concern with mobile technology was clusters of the disease around those living near phone masts. One study in Israel found a 4.5-fold increase in cancers of all kinds in the immediate vicinity of a mast (Int. J. Cancer Prev., 2004). In 2009, a Korean team of researchers carried out a pool analysis of the results of 23 studies, which involved almost 38,000 subjects.
