Abstract:SUMMARY Standard models of radiation action do not accurately describe survival at low clinically relevant X-ray doses. This was made evident by survival experiments using methods which assayed a precise number of cells. At extremely low doses of X-rays (< ~0 . 5 Gy) a hypersensitive response exists which results in an inflection in the survival curve describing the response of many cell lines. In the case of sparsely ionizing radiations, this sensitive response is typically followed by an increased resistant … Show more
“…Continuing to use mainly the example of treatment of cancer by radiation and the response to low doses (Figure 1) as an example (Skov and Marples), 7 the answer is`probably'. In cell lines at least, there seems to be a correlation between the intrinsic radiosensitivity (SF 2 ) and the extent of IRR.…”

“…Assim, seria diminuída a radiorresistência que está presente em baixas doses, sendo este um dos mecanismos citados nos estudos de Skov nestas faixas de radiação [135].…”
