Should ALARA concept be terminated

Mohan Doss
Radiation is everywhere in the universe. To demand that radiation from nuclear medicine and nuclear energy sources be lower than or less than even several multiples of background radiation is counterproductive to use of these sciences technologies

Mohn Doss, Medical Physicist in Diagnostic Imaging. The ALARA concept, As Low As Reasonably Achievable is base on the linear no-threshold (LNT) model assumption and / or low--dose radiation cancer concerns. Do mutations increase linearly with radiation dose? When radiation dose increases, at low doses, mutations decrease. Cancers do not increase linearly with mutations. There are many more reasons to conclude: Mutation model of cancer is not valid. See for example slide 6 / 13.
