RF Energy and the Human Body

Much of the confusion  and  concern  over exposure to RF energy comes from confusion over the two forms of radiation that people might encounter.
Think Hiroshima , Nagasaki , Chernobyl , X-rays , and Uranium  and everybody gets concerned . Radioactive materials and X-rays  generate  what is known as  ionizing radiation  , which can be very dangerous ionizing radiation  kills  or damage human cells , its effects are cumulative  and there is no practical minimum . So , continuous exposure to low levels of ionizing radiation can eventually lead to serious health problems. Just getting an x- ray kills or damage millions of  cells in our body. But our body will repair itself   within short period , providing there is no additional exposure . However , the person  giving you the X-ray has to be very careful to get behind  the lead in the door so that they don't get exposed. This exposure  would be repetitive and cause  cumulative  effects.
In contrast, radio frequency energy and the energy from most of the light frequencies are forms of  non-ionizing radiation. This form of energy can heat  tissue  when it is concentrated enough and is the principle behind  the common microwave oven. Exposure to  very tiny amounts of RF energy has much less impact on us  than if  the temperature in the room we are in were to change by a small  fraction to over exertion  degree. Problems occur.
of a  with exposure to RF energy only when it is so concentrated that our body has a problem dealing with the excess heat. The effects are very similar .
