Radiation-induced micronuclei in hospital workers dealing with diagnostic x-rays

Cytokinesis is blocking method was employed to perform micronucleus assay on a group of hospital workers exposed, occupationally, to diagnostic x- rays at levels below the maximum permissible limit It was found that the yeild of micronuclei in the lymphocytes from hospital workers was significantly higher than the corresponding value in a group of healthy controls. In addition to the classical scheme of observing the micronuclei in binuclear cytokines is blocked cells, a trial was made to include the yields of micronuclei in mono-. tri. and quadrinuclear cells into the calculation. The findings were compared with that noticed in groups of healthy controls and radiation workers
