background: health hazards associated with exposure due to the natural radioactivity which is a part of our physical environment are of great concern. in order to assess the risks associated with exposure due to the natural radioactivity in soil and building materials, extensive studies have been carried out all over the world. the most commonly encountered radionuclide’s are 238u, 232th, their...

background: natural background radiation of a particular region is one of the distinctive factors defining the status of environment. eloor island is an industrial area in ernakulum district of the state of kerala, india. the indoor and outdoor gamma level measurements have been carried out for the region for evaluating the annual effective dose to the population residing in this area. material...

introduction natural and artificial radionuclides are the main sources of human radiation exposure. these radionuclides, which are present in the environment, can enter the food chain. rice is one of the most important food components in iran. radionuclides by transferring from soil to rice and entering the human body can affect human health. materials and methods fourteen samples of different ...

in this study, natural and artificial radioactivity concentration in agaricus bispora (nourished mushroom) and their composts, cantharellus cibarius and coprinus micaceuc (wild species) were determined. samples were collected from sahne and two kinds of wild mushroom species from songhor koliai township gardens all located in kermanshah province were collected. hpge gamma ray spectrometry syste...

This paper presents data on the content of toxic elements (Mn, Ni, Zn, Cu, Pb, As, Cr, Cd and Co), technogenic (137Cs, 134Cs) natural radionuclides 238U 232Th series (234Th, 226Ra, 210Pb, 232Th) 40K in sediments collected from ten sampling stations along northern Bulgarian Black Sea coast for a period more than twenty years. Measurements were made by Gamma Spectrometry Inductively Coupled Plasm...

Introduction Natural and artificial radionuclides are the main sources of human radiation exposure. These radionuclides, which are present in the environment, can enter the food chain. Rice is one of the most important food components in Iran. Radionuclides by transferring from soil to rice and entering the human body can affect human health.

High concentrations of natural radionuclides in building materials can result in high dose rates indoors, from both internal and external exposure. In dose calculations, the main radionuclides of interest are 226Ra, 232Th and 40K. Usually much attention is paid to 226Ra due to 222Rn exhalation and the subsequent internal exposure. Other radionuclides of the uranium series such as 238U and 210Pb...
