Fig. 2From: Non-linear dose response of DNA double strand breaks in response to chronic low dose radiation in individuals from high level natural radiation areas of Kerala coastBox plot showing distribution of basal level frequency of γH2AX foci / cell in peripheral blood mononuclear cells of individuals (n = 200) from different back-ground dose groups. Dose group ≤ 1.50mGy/year is considered as NLNRA (control group). Dose groups such as 1.51-5.0mGy/year, 5.01 -10.0mGy/year, 10.01-15.00mGy/year, and > 15mGy/year are considered as HLNRA (exposed group). NLNRA: Normal level Natural radiation areas; HLNRA: High level natural radiation areaBack to article page
