With traces of radioactive material from Fukushima appearing in rainwater as far away as Boston, concerns about radiation exposure are at an all-time high. But even if you're not anxious about contamination from Japan, you may be wondering about the health risks associated with everyday sources of radiation — from the sun to airport scanners and routine medical procedures like mammograms and CT scans.
But if scientists from University of Toronto are right, you may not have to worry as much about the damage from X-rays in coming years. Reporting at the annual meeting of the Society of Interventional Radiology, Dr. Kieran Murphy, a radiologist at the university, said that a cocktail of antioxidants he and his team have developed could cut the damage done to DNA by radiation from CT scans by as much as 50%, if taken before the scan.
