Hotting Up

There is so much confusion nowadays about the pros and cons of radiation I thought it best to try and clarify it as best I could. People are exposed to non-ionising radiation through natural sources such as the sun as well as human-generated sources like computers, microwave ovens, mobile phones, radar systems and power lines. From the sun, UV radiation is a major concern related to sunburn, skin damage and skin cancer. Too much sun can have a negative effect on one's immune system. On the other hand, without enough exposure to the sun, the body does not produce Vitamin D. But more on that at a later date.
