[Modification of the radiosensitivity of cultured "Vero" cells by cumene hydroperoxide]. / Modification de la radiosensibilité de cellules "Vero" en cultures par l'hydroperoxyde de Cumène.

Cumene-hydroperoxide is a radical reaction promoter. Vero cells monolayers treated with this compound were irradiated with gamma-rays and their radiosensitization was compared with that of irradiated, non-treated control cells. Cumene-hydroperoxide treated cells showed a paradoxal radioresistance. We propose a possible buffer-like effect of cumene-hydroperoxide to explain these results.
