Introduction: Artificial and natural radionuclides exist in the environmental materials, such as water, soil, rocks, and plant as well as in animals and human body tissues. Therefore, human being and environment are at constant radiation exposure. Regarding this, the present study aimed to determine the specific activities of radionuclides and perform the risk assessment wheat and barley sample...

The primary goal of the Agency was originally to accurately assessthe effects of human exposure to single chemicals in a single medium (e.g.water) over a human l...
Many different quantitative techniques have been developed to either assess Environmental Justice (EJ) issues or estimate exposure and dose for risk assessment. However, very few approaches have been applied to link EJ factors to exposure dose estimate and identify potential impacts of EJ factors on dose-related variables. The purpose of this study is to identify quantitative approaches that in...
introduction artificial and natural radionuclides are found in diverse environmental compartments, such as water, soil, rocks, vegetables, animals, and human body tissues. as such, humans and environments are at constant exposure of these radiation types. in this research investigated specific activities of radionuclide and dose assessment of some species of mushrooms. materials and methods in ...
