A study was done on DNA damage in tissue cells of ranon-inhaled rats. Sprague-Dawley rats were exposed to radon and its progeny to doses of 66, 111 and 174 WLM(working level month), respectively. Single cell suspensions of the rat lung, spleen and thymus were prepared. Single cell gel eletrophoresis(SCGE) was performed to detect the length of DNA migration in the rat peripheral blood mononuclear cells(PBMC), bronchi alveolar lavage fluids (BALF)cells, lung cells, spleen cells and thymus cells. DNA migration in the rat PBMC, BALF cells and lung cells increased with cumulative doses. The dose-effect relationships of the DNA damages and a correlation between DNA migration in PBMC and lung cells could be established. Radon and its progeny could cause DNA strand break in rat PBMC, BALF cells and lung cells.
