Cesium-137 activity concentrations in soil and brick samples of Mirpur, Azad Kashmir Pakistan
Background: The aim of this study was to measure137Cs levels in soil and brick samples to set the baseline data and an indicator of fallout radioactivity for this part of the world. This study will help to probe, if there is any health threat posed by 137Cs exposure to the residents of the area. Materials and Methods: Twenty five samples of soil and 6 samples of bricks were collected from diffe...

متن کاملSpatial Variability and Cesium-137 Inventories in Native Forest
With the nuclear fission discovery and development of nuclear weapons in 1940s, artificial radioisotopes were introduced in the environment. This contamination is due to worldwide fallout by superficial nuclear tests realized from early 1950s to late 1970s by USA, former URSS, UK, France and China. One of theses radioisotopes that have been very studied is cesium-137. Cesium-137 has a half-life...
متن کامل01.09 Radioactivity in Soils (Cesium-134 and Cesium-137) (Edition 1992)
The reactor accident at Chernobyl on 26 April 1986 dramatically demonstrated the dangers involved in man-made radioactivity. The Chernobyl catastrophe was incomparably larger than the reactor accident in Harrisburg, USA in 1979. Chernobyl released enormous amounts of radioactive substances. Wind and weather dynamics transported these substances and deposited them onto the earth as radioactive d...
متن کاملOccurrence and Cesium-137 and Other Radionuclides in the Surface Layers of Soil in Ohio and Antarctica
The testing of nuclear weapons in the atmosphere in the 1960s and the accidental explosion of a nuclear reactor in 1986 near Chernobyl, Ukraine, caused large amounts of fission-product radionuclides to be deposited over most of the surface of the Earth. The present study was undertaken in order to compare the decay rates of Cs in the surface layer of soil in central Ohio at 40°N and in Antarcti...
