Radioprotective influence of Mentha piperita (Linn) against gamma irradiation in mice: Antioxidant and radical scavenging activity.

abstract：:A/J and C57BL/6J mice, strains which differ in susceptibility to chemical-induced lung tumours, were examined for differential sensitivity to radon-induced lung cancer. Sixty weeks after exposure to 952 WLM radon (3.34 J h1 m-3), no lung tumours were found in the control, sham- (one dust-) exposed, or radon-exposed C5...
