Evaluation of public exposure in high background natural radiation areas (HBNRAs) of Ramsar
Some areas in Ramsar, a northern city of IRAN, have the most natural radiation level in the world which is due to high concentration of 226Ra and its daughter products specially 222Rn and therefore these regions have been interested for radiation related investigations. The aim of this study also has been to evaluate public exposure in such areas in Ramsar, in order to obtain up to date informa...
متن کاملThe High Background Radiation Area in Ramsar Iran: Geology, Norm, Biology, Lnt, and Possible Regulatory Fun
The city of Ramsar Iran hosts some of the highest natural radiation levels on earth, and over 2000 people are exposed to radiation doses ranging from 1 to 26 rem per year. Curiously, inhabitants of this region seem to have no greater incidence of cancer than those in neighboring areas of normal background radiation levels, and preliminary studies suggest their blood cells experience fewer induc...

Some Areas of Ramsar, a city in northern Iran are among the world’s wellknown inhabited areas with highest levels of natural radiation. Annual exposure levels in these areas are up to 260 mGy y‐1 and the mean exposure rate is about 10 mGy y‐1 for a population of about 2000 residents. If elevated levels of natural radiation as high as a few hundred mSv per year is detrimental to health and...

15 صفحه اولCan recent Berkeley findings help us to find a solution to the paradox of cancer incidence in high natural background radiation areas of Ramsar, Iran?
According to the report published by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) in 2000, Ramsar city in northern Iran, has some inhabited areas with the highest known natural background radiation levels in the world (1). The annual radiation absorbed dose in high background radiation areas (HBRAs) of Ramsar is extraordinary high, reaching 260 mSv that i...
متن کاملEvaluation 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...
