Mitogenic Stimulation of Peripheral Lymphocytes from Radium Workers

The increased incidence of malignancies among patients exposed t o radium either occupationally or therapeutically, has encouraged many studies into the multiple effects of ingested radium and other bone-seeking isotopes. The purpose of the authors' studies is to determine (1) if immunological impairment occurs in patients exposed to radium and (2) whether such impairment, if present, is associated with tumor development.
