Report says CT scans exposed youngsters to levels equivalent to 4,000 X-rays

Editor's note: By all means everyone should try hard enough to avoid getting x-ray imaging. At least, X-ray imaging should not be done just to quench doctors’ curiosity. One of the risks you may never know is that radiologists seldom measure the dose, according to Dr John Gofman, a noted physicist and physician, who found 75 percent of breast cancer cases is linked to medical x-ray exposure. He said the dose for a single x-ray can vary by a factor of ten because radiologists never measure the dose. Some reports said 30 percent of x-ray exposure is unneccessary, meaningless or senseless.
