Radionuclide Activity Concentrations in Some Wild Fungi and Nourished Mushrooms and Their Composts
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 collecte...
متن کاملAssessment of Radioactivity Contents of Food in the Oil and Gas Producing Areas in Delta State, Nigeria
The radioactivity concentrations of 40 K, 238 U, 232 Th and 137 Cs in eighteen species of foodstuffs in the oil and gas producing areas in Delta State, Nigeria have been measured using a high purity germanium, (HPGe) detector system. The mean specific activities of 40 K, 238 U, 232 Th and 137 Cs vary between 36.48 – 68.02; 2.33 – 5.18; 1.26 – 2.98 and 0.27 – 2.47 Bq kg -1 respectively in vegeta...
متن کاملRadioactivity in the Mediterranean flora of the Kaštela Bay, Croatia.
This study refers to background activity concentrations of (238)U, (226)Ra, (232)Th, (208)Tl, (40)K, and (137)Cs in soil and plants of the Kaštela Bay, Croatia and related plant-soil concentration ratios (CR's). Fourteen different Mediterranean plant species growing in natural conditions have been included and were divided into three major plant groups (grasses and herbs, shrub, tree). Radionuc...
متن کاملMeasurement of 226Ra, 232Th, 137Cs and 40K activities of Wheat and Corn Products in Ilam Province – Iran and Resultant Annual Ingestion Radiation Dose
BACKGROUND BACKGROUND Natural background radiation is the main source of human exposure to radioactive material. Soils naturally have radioactive mineral contents. The aim of this study is to determine natural ((238) U, (232) Th, (40) K) and artificial ((137) Cs) radioactivity levels in wheat and corn fields of Eilam province. METHODS HPGe detector was used to measure the concentration act...
متن کاملSearch for TENORM in the Tisza River sediment.
Sediment samples from the Tisza River in Serbia were investigated for possible TENORM pollutants. The radionuclide content of the samples was determined by means of low-level high-resolution gamma-spectroscopy. In addition to the members of the natural radioactive chains of (238)U and (232)Th and the natural (40)K, Chernobyl origin (137)Cs was detected in 26 of the 28 samples tested. The higher...
