Chemical Risk without Concurrent External Exposure!

Assessment 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...

Assessment of the External Exposure Dose to Humans From

At present the Baltic Sea is considered to be the most contaminated with anthropogenic radionuclides in comparison to any other part of the World Ocean. Anthropogenic radionuclides (mainly 137 Cs and 90 Sr) found in the seawater are sources of the external exposure that contributes to the total radiation exposure to humans. The variations of activity concentrations of 137 Cs and 90 Sr in the wa...

the study of aaag repeat polymorphism in promoter of errg gene and its association with the risk of breast cancer in isfahan region

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...

Assessment of lung cancer risk due to indoor radon exposure in inhabitants of the state of Azad Kashmir Pakistan

Background: Several epidemiological studies conducted on underground miner’s show that exposure to elevated levels of radioactive radon gas is expected to increase the risk of lung cancer. Relative risk of lung cancer is almost linear with radon exposure. Elevated concentrations of radon are not only reported within mines but also for closed indoor environment of general public houses....
