The concentration of anthropogenic 137Cs and naturally occurring 226Ra, 232Th 40K radionuclides were measured in the undisturbed soil at 0-5 cm depth water collected from natural reservoir Terrene Goainghat Jaintapur area Sylhet district Bangladesh near Indian border by gamma ray spectrometry, with aim evaluating environmental radiation hazard. activity was observed all samples, ranging 5.22 4 ...

This study is aimed at assessing radiation hazards associated with natural radioactivity in common building materials used Ho Chi Minh City, Vietnam. Thirty-six samples from eighteen types of were collected to measure activity concentrations using the gross alpha/beta counting system and gamma-ray spectrometry. The alpha beta ranged 94.7 ? 31.3 1045.1 112.3 Bqkg-1 104.9 4.7 834.4 37.1 Bqkg-1, r...

Introduction: The present study investigated the relatively high concentrations of natural radionuclides in raw material that used in ceramic manufacturing, and estimated the occupational exposure due to these activity concentrations. Material and Methods: A high-purity Germanium detector was used to determine naturally occurring radionuclide...

background: this study consists of two parts. the first part deals with both qualitative and quantitative analysis of 226ra using alpha spectrometry measurement method. in the second part, the percentage of radioactive equilibrium between 226 ra and its daughter products were determined by alpha spectrometry and total alpha measurement system after elapsed time of 15 days from precipitation. ma...

Medicinal plants are very useful for humans with the various molecules and vitamins they contain. Most of that grow spontaneously in nature were taken into agricultural production practices after their healing properties discovered. The use pure active ingredients obtained from is quite common. These effective compounds also used by pharmaceutical industry preparation modern drug formulations. ...
