Epidemiology so far fails to substantiate the claim of an increase in cancer incidence in humans following low-level exposure to ionizing radiation, below about 100 mGy or mSv.

The LNT model was introduced as a concept to facilitate radiation protection. But the use of this model led to the claim that even the smallest dose (one electron traversing a cell) may initiate carcinogenesis—for instance, from diagnostic x-ray sources. This claim is highly hypothetical and has resulted in medical, economic, and other societal harm.
Zbigniew Jaworowski was chairman of the Scientific Council of the Central Laboratory for Radiological Protection in Warsaw and Chair of the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). He was a medical doctor with PhD and DSc in natural sciences.
Margaret N. Maxey: In his book, "Has Radiation Protection Become a Health Hazard?" Gunnar Walinder, a Swedish radiobiologist, states unequivocally: "The Linear, No-Threshold Hypothesis is one of the greatest scientific scandals of modern times."
