Lowell Technological Inst., 1971. Bias was introduced by funding to support radiation protection rather than establish the role of ionizing radiation in biology and health, and to assess the beneficial effects found. No evidence supports the LNT hypothesis.
Substantial evidence contradicts it, with natural levels beneficial, even essential.
Doses below background levels are detrimental. Low-doses stimulate immune functions, and have been used to successfully treat and prevent cancer. However, radiation science policy has acted to ignore and suppress evidence of beneficial effects and to prevent confirmatory research. There is a high public cost for zero health benefit to society, and the loss of nuclear science and technology contributions to humanity.
