Mohn Doss, Medical Physicist in Diagnostic Imaging: Mohan Doss and Edward Calabrese with life time careers studying low dose radiation and low dose toxins are ignored by this writer for Discover Magazine. Instead he focuses on trying to convince his readers that low dose radiation is dangerous and should not be used or tolerated in modern society. He ignores all the benefits of low dose radiation in diagnostic and therapeutic nuclear medicine and in having affordable and safe nuclear energy. That's what the media so often does. Very unfortunate.

Mohn Doss, Medical Physicist in Diagnostic Imaging: 1) Low-dose radiation increases activation of natural killer cells. 2) Natural killer cells eliminate cancer cells, and so there would be less cancers following exposure to low-dose radiation.

Mohn Doss, Medical Physicist in Diagnostic Imaging: The LNT Era (Linear No Threshold) has not ended yet. But, there are signs that we may be approaching its end. The problem with the LNT model for radiation-induced cancer is the absence of threshold results in the fear of the smallest amount of radiation. The LNT model was adopted by advisory bodies in the 1950 and has been endorsed by them repeatedly. Low-dose radiation boosts the immune system and so it should lead to reduction of cancers, a phenomenon known as radiation hormesis. Conclusion: The LNT mmodel is not valid and lives are being lost because of the LNT model and unjustified fear of low-dose radiation.

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.
