I don't know why but I just can't seem to get over my fear of being exposed to radiation by anything. I was so afraid of it that I have used a cell phone only three times in the past year and a half. I've contemplated quitting my job because I use wireless headsets - use to be up to 5 hours a day, 5 days a week, now I almost always refuse to wear one - for about 2 and a half years.
I worry all the time by saying "will this exposure amount give me a brain tumor?" Or even a cell phone tower, or dental x-ray. How much radiation do we need to cause harmful effects on our bodies?
