Despite growing awareness of health risks from x-rays, radiation is on the rise in dental offices - thanks to the growing "indiscriminate use" of CT scans, which pump out as much as 60 times the radiation of conventional dental x-rays.
Read how a dental x-ray radiation could affect your health, what authorities are doing to minimize it (or not!) and what you can do about it in this story I just did in Vancouver's Georgia Straight weekly.
See more background on the problem in this New York Times investigation, which revealed that questionable marketing has fueled an explosion in the use of cone-beam CT scanners in dental offices.
