Jerry Cuttler - Cuttler & Associates, Inc. Toronto, Ontario, Canada explains the science of low dose radiation.

James Muckerheide - Low-dose, low-dose-rate, radiation enhances biological responses: for immune systems, enzymatic repair, physiological functions, and apoptotic removal of cellular damage, etc., enhancing biological capability and health, including prevention and removal of cancers and other diseases.

Low level radiation research has also shown no adverse effects in studies with the power to demonstrate such effects. Studies have shown beneficial biological and health effects in many substantial human biological and epidemiological studies, and animal experiments.

However, radiation protection policies and rules do not consider such valid data.

Mohan Doss.Medical Physics, Vol. 40, No. 3, March 2013 In summary, the two observations, (i) the ultimately counter-productive effect of some antiangiogenesis therapies because of ignoring adaptive response of tumor cells, and (ii) the effectiveness of incidental adaptive response (enhanced immune response due to low dose radiation to parts of the body) in eliminating untreated lesions at sites away from the high dose radiation-treated tumors, demonstrate the potential importance of considering adaptive response when estimating biological effects from external agents such as radiation.
