A major study conducted by the National Toxicology Program has found a positive correlation between radio-frequency radiation exposure (like that given off by phones) and certain cancers in rats — though only male ones. The two-year, peer-reviewed study involved thousands of rats, each of which received one of several carefully controlled doses of radiation daily for two years (including a control group that received no radiation at all). Two to three percent of rats exposed developed glioma in the brain, and one to six percent developed schwannoma of the heart. There are three main reasons why people are concerned that cell phones (also known as “mobile” or “wireless” telephones) might have the potential to cause certain types of cancer or other health problems.

• Cell phones emit radiofrequency energy (radio waves), a form of non-ionizing radiation, from their antennas. Tissues nearest to the antenna can absorb this energy.
• The number of cell phone users has increased rapidly. As of December 2014, there were more than 327.5 million cell phone subscribers in the United States, according to the Cellular Telecommunications and Internet Association. This is a nearly threefold increase from the 110 million users in 2000. Globally, the number of subscr iptions is estimated by the International Telecommunications Union to be 5 billion.
• Over time, the number of cell phone calls per day, the length of each call, and the amount of time people use cell phones have increased. However, improvements in cell phone technology have resulted in devices that have lower power outputs than earlier models.
  

What are your opinions on phone radiation? Should we be more cautious and aware of it's harmful effects? Should children at the age of 10 and below be allowed cell phone access?
