Guest guest Posted January 12, 2008 Report Share Posted January 12, 2008 I work in the medical field, Having a ct scan is like having the equivalent to 6 chest x-rays. However if ct scans can help detect a more ominous condition, such as cancer, brain tumor etc, it is a necessary diagnostic tool. Excerpt : "Our universe and solar system is and always has been radioactive. We live in a naturally radioactive world. Background radiation accounts for an individual receiving, on the average, about 300-350 mrem each year. For example, a cross country airplane flight results in a dose of 4 mrem per trip. A routine chest x-ray is about 10 mrem per film. Smoking 1.5 packs of cigarettes daily exposes the individual to about 1300 mrem per year. " So can you imagine people who fly all the time, or around second hand smoke etc. etc. Of course then there is Radon exposure etc. etc. and exposure from brick buildings etc etc. We also irradiate our food! Some cancers are caused by virus-- scary huh? It's just the type of world we live it! My philosophy is that a healthy immune can thwart some of the bad stuff we are exposed to. We try our best to eat healthy despite genetics and environment !! Joan I Quote Link to comment Share on other sites More sharing options...
