In an article published in the June 2017 issue of The Journal of Nuclear Medicine, researchers assert that exposure to medical imaging radiation not only doesn’t increase an adult person’s risk of getting cancer, it doesn’t increase a child’s risk. According to the authors, the long-held belief that even low doses of radiation, such as those received in diagnostic imaging, increase cancer risk is based on an inaccurate, 70-year-old hypothesis and leads to unnecessary fear and misdiagnoses.

The hypothesis referred to is the linear no-threshold hypothesis (LNT) promoted by Nobel Laureate Hermann Muller in 1946. Muller stated that the dose-response relationship is linear with no threshold dose, i.e., all radiation is harmful, regardless of how low the dose and dose rate.
