In the work, we investigate the adaptive response of Hela cells and dermal human fibroblast on exposure of LDR. The culture cells were irradiated on an Xstrahl 300, which produces X-rays with 200 keV energy. Studies have shown that adaptive response induced by Low-dose radiation (LDR) is manifested in DHF cells. LDR does not induce the radioadaptive response in tumoral Hela cells. We have found an increase in the radiosensitivity to ionizing radiation in Hela cells
