  • Title: Gamma rays: further evidence for lack of a threshold dose for lethality to human cells.
    Author: Furcinitti PS, Todd P.
    Journal: Science; 1979 Oct 26; 206(4417):475-7. PubMed ID: 504991.
    Abstract:
    In experiments designed to measure human cell survival sith +/- 2 percent accuracy it was found that low doses (21 to 87 rad) of gamma-rays inactivated the colony-forming ability of cultured human cells with a probability of 0.00226 +/- 0.00012 per rad. There appears to be no threshold for the lethality of radiation to human cells in vitro.
