Is it time to shed some light on the black box of health policies regarding the inhabitants of the high background radiation areas of Ramsar?
Although there are substantial experimental, epidemiological and clinical evidences that high doses of ionizing radiation cause cancer and other detrimental biological effects, the health effects of human exposure to chronic low dose radiation exposures are still poorly known. People in some areas around the world live in dwellings with radiation and radon levels as much as more than 2...
متن کاملCan 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 کاملAlterations of PSA, CA15.3, CA125, Cyfra21-1, CEA, CA19.9, AFP and Tag72 tumor markers in human blood serum due to long term exposure to high levels of natural background radiation in Ramsar, Iran
Background: Ramsar (Mazandran province) is known for its extremely high levels of natural background radiation. Although no excess cancer rate is reported in these areas by epidemiological studies, the study of tumor markers in the inhabitants of these areas may shed some light on the impact of high levels of background radiation on cancer induction. Materials and Methods: The level of backgrou...
متن کاملNatural ventilation considerations for radon prone areas of Ramsar
Background: In Iran, architectures are often unaware of the risk of radon inhalation and how to reduce radon levels. Furthermore, radon considerations are not implemented in construction methods, construction materials and building utilization by regulatory authorities. Materials and Methods: In this study after reviewing the meteorological changes of Ramsar over the past 50 years (1955-2005), ...
متن کاملInvestigation of the Efficacy of Damp-Proof Montmorillonite Nanoclay for Radon Reduction Strategies in Radon Prone Areas of Ramsar
Background: Ramsar, a northern city in Iran, lies on the coast of the Caspian Sea. This city has areas with some of the highest levels of natural radiation measured to date. The radon concentration in some areas of Ramsar is up to 3700 Bq m–3. On the other hand, due to high level of humidity, damp-proof barriers should be used in construction of new buildings in radon prone areas of this cit...
متن کاملAssessment of Effective Dose Equivalent from Internal Exposure to 222Rn in Ramsar City
Introduction In this study, effective dose equivalent for the public due to internal exposure to 222radon (222Rn) was evaluated in three regions of Ramsar, a northern coastal city in Iran. Materials and Methods Measurements were carried out using a radon monitoring device. Outdoor and indoor radon concentrations were measured within 24 hours with an integration in...
