natural radionuclides present in soil as well as certain anthropogenic radionuclides released to the environment are the major contributors to terrestrial outdoor exposures. in the assessment of human exposures from environmental radioactivity, besides the conventional method of soil and vegetation sampling combined with laboratory based analyses of environmental media, the other choice would b...

Introduction: The present study was conducted to measure the specific activities of 226Ra,232Th and 40K, in some samples of nuts collected from the local markets in Iraq. In addition, this study sought to calculate the annual effective dose of gamma ray to children and adults. Material and Methods: The quantification of radionuclides was accomplished by gamma spectrometry NaI (Tl) detector. Res...

gamma-rays emitted from the ground surface relate to the primary mineralogy and geochemistryof the bedrock, and the secondary weathered materials. this information can contribute significantly to anunderstanding of the geochemical and pedogenetic history of a region. the main aim of this paper was to study the relationship between ground gamma-ray data and basement geochemistry in the lese catc...

The aerial measuring terrestrial gamma radiation from airborne platforms is a useful method for characterizing the radiation levels over large areas. Because of the advantage of Monte Carlo method, it is very suitable for simulation of gamma ray transport and interaction with media (soil, air, aircraft and detector), which offer alternative means of estimating detector response and calibration ...
