Evaluation of gene expression of MLH1 and MSH2 between inhabitants of High Background Radiation Areas in Ramsar, Iran

Introduction: Annual effective radiation dose from all natural sources is approximately about 2.4 mSv and contribution of unnatural or man-made sources is 0.8 mSv. In some places of Ramsar, radiation dose due to radon exposure is about 3700 Bqm -3 while according to US EPA instruction radon levels should be 200 Bq m-3. Amazingly, there is not a meaningful result in the studies...
