Update on the Debate on Radiation Hormesis as of November 1, 2020

Radiation Hormesis was Not Refuted in the the Online Debate! 


A large number of scientists were invited via email to participate in the debate on radiation hormesis (as seen in the announcement below) during Aug 31, 2020 to Oct 1, 2020. The invitees included leading proponents of the LNT model, representatives of many organizations which support and/or use the LNT model, authors of articles which utilize the LNT model, etc., as well as scientists who do not support the LNT model. At the end of the debate period (Oct 31, 2020), none of the evidence for radiation hormesis had been refuted in the debate website. In addition, four of the pieces of evidence for radiation hormesis were not refuted in an earlier short dialogue with NCRP, a premier proponent of the LNT model. 

If radiation hormesis is valid, as indicated by the absence of refutation of the supportive evidence, in
spite of multiple opportunities presented to the LNT model supporters, it logically follows that the LNT model is invalid, and the present radiation protection recommendations and practices are leading to increased cancer risk. Individuals and organizations who make such recommendations are asked to discontinue these recommendations unless they can refute radiation hormesis. 

Though the official debate period is over and the result has been declared, you are welcomed to refute the evidence by posting your arguments at the debate website. If any of the evidence is refuted, it will be recognized in the debate dashboard below and the results here will be updated.
