I don't know whether TFT helps with radiation side effect, do you know any other methods for minizing radiation demage?
Yes, EFT for one http://www.emofree.com.
There are electronic frequencies; reference Clark and Rife. I have found that using the frequencies [zapping] and EFT [tapping] simultaneously provides the Innate some wonderful tools to do just about anything respecting curing, healing, detoxing the body.
There are homeopathics for radiation and for some people, Thioctic Acid aka Alpha Lipoic Acid.
