Jerry Cuttler: Although almost 120 years of medical experience and data exist on human exposure to ionizing radiation, advisory bodies and regulators claim there are still significant uncertainties about radiation health risks that require extreme precautions be taken. In the `950s, without scientific evidence, the Natitonal Academy of Sciences Biological Effects of Atomic Radiation (BEAR) Committee recommended that the linear no-threshold (LNT) model be used to assess the risk of radiation-induced mutations in germ cells and the risk of cancer in somatic cells.
