Physiological and pathophysiological aspects of the immune system contributing to a biomathematical model of lymphocytes.

The effects of chronic low-dose irradiation on the immune system and the lymphocytes are largely unknown. The uranium miners in the former German Democratic Republic (GDR) were exposed mainly to a local low-dose irradiation in the lung by radon and its progeny, but also to some whole-body gamma irradiation. The local irradiation led to an increased rate of lung cancer and perhaps to some increase in extrapulmonary neoplasms.
