Cancerblock keeps you safe by reducing your phone’s radiation energy and extends battery life. 10% goes to cancer research! Cancerblock is an application that limits exposure to a cell phone’s radiation energy. Cancerblock cycles on and off a cell phone radiation energy sources, thereby limiting exposure to the known and unknown side effects of extended cell phone use. With a default schedule of 15 minutes off and 1 minute on, a user of Cancerblock reduces their radiation exposure by 9,408 minutes in one week or a total reduction of 93.33%! Cancerblock has both programmable and default settings as well as a simple user interface allowing users to customize the application to their schedule. The developers hope that Cancerblock will help users better understand the radiation risks, including cancer, associated with extended exposure to cell phone use while also keeping your phone functional and safe. A cell phone’s SAR, or its Specific Absorption Rate, is a measure of the amount of radio frequency (RF) energy absorbed by the body when using a handset. All cell phones emit RF energy and have SAR ratings that vary with each cell phone model. SAR ratings are at their highest levels in today’s high-power "smart phones". This is exactly why Cancerblock has been developed.
