Stimulation of antioxidant machinery in rats by low dose ionizing radiation: a concept of radiation hormesis.

Abstract

OBJECTIVE:

The concept of radiation hormesis has been the matter of discussion with regard to beneficial effects to biological systems from low doses of ionizing radiations. However, its molecular basis is not well understood till now and the present study is a step forward to elucidate how low levels of ionizing radiation prove beneficial for functioning of biological systems.
