| Summary: | The Sykes commentary advocates “a more sensible, graded approach for protection from low dose ionizing radiation” until the LNT dose-response issue is resolved. It urges scientists to stop criticizing the LNT model that links radiation to a risk of cancer and accept regulatory use of the threshold model to “protect” people, but with higher limits. It fails to mention the 120-year history of successful low-dose treatments of a wide variety of serious diseases, including cancers. The commentary ignores published evidence of a threshold at 1.1 Gy for radiogenic leukemia and a dose-rate threshold at about 0.6 Gy per year for lifespan shortening. LNT came from politicized science, replete with scientific misconduct and conflict of interest. Its acceptance created a false cancer scare that was likely intended to stop atomic bomb testing, but it has severely damaged human welfare. Many vitally important low-dose therapies were discarded when the radiation scare was disseminated in 1956. The rapid growth of nuclear energy ended with the media-inflamed public panic after the Three Mile Island accident in 1979. Extreme implementation of the precautionary principle made it uneconomic. Availability of a low-dose therapy for lung inflammation could have dramatically decreased the impact of the COVID-19 pandemic.
