No Evidence of Cancer Risk from X-rays.

No Evidence of Cancer Risk from X-rays.

A study published in the American Journal of Clinical Oncology concludes there is no proof that low-level radiation from medical imaging—such as X-ray and computed tomography scans—causes cancer. The authors of the study claim that the model used to estimate cancer risk is wrong and should be abandoned. According to the researchers, the current model called linear no-threshold ignores the fact that the human body is able to repair damage caused by low dose radiation. Humans and other organisms have been continually exposed to naturally occurring background radiation in the environment for thousands of years with no associated health effects.

The authors note, "We are literally bathed every second of every day in low-dose radiation exposure due to natural background radiation, exposures that vary annually from a few mGy to 260 mGy, depending upon where one lives on the planet."
