Gamma Ray Monitoring

A chronic very low dose of gamma–rays alters cell adhesion

The biological effects of very low doses of ionising radiation are difficult to assess. We previously observed a delay of death by lymphoma in two different mouse strains continuously irradiated (γ–rays) with a dose rate of 10 cGy year−1. Cellular mechanisms likely to lead to slowing tumour growth were explored. Human lymphoid and epithelial cell lines (HL60 an
