Some researchers claim that, despite wide belief, that exposure to Low-Dose Ionizing Radiation (LDIR) from computed tomography (CT) and X-ray medical imaging scans does not cause cancer.

Jeffrey Siegel and Charles Pennington wrote a 2015 article for Skeptic magazine arguing that the "Linear No Threshold" model for was not supported by evidence, and that using this model to predict that LDIR was carcinogenic was incorrect.

Eureka Alert report that James Welsh, MD, made a similar claim in a paper published in the American Journal of Clinical Oncology.

Is there evidence to support or reject the idea that the radiation received from medical imaging equipment poses a cancer risk?

Is there evidence to support or reject the idea that the low-dose radiation received from medical imaging equipment poses a cancer risk?

Researchers such as Jeffrey Siegel and James Welsh report that exposure to computed tomography (CT) medical imaging scans and X rays do not cause cancer since we are bathed every second of every day in low-dose radiation that vary annually from a few mGy to 260 mGy. So are there any well known negative health effects or documented cancer cases caused by either temporary or high exposure to low dose radiation of X-rays, CT scans or other medical imaging?
