Application of Radioactive Fallout Cesium-137 for Measuring Soil Erosion and Sediment Accumulation Rates and Patterns: A Review
Radioactive fallout 137CS (cesium-137) deposited across the landscape from atmospheric nuclear tests is strongly absorbed on soil particles limiting its movement by chemical and biological processes. Most 137CS movement in the environment is by physical processes; therefore, 137CS is a unique tracer for studying erosion and sedimentation. Cesium-137 loss from a watershed has been shown to corre...
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 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 کاملCesium-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 کاملBiological proliferation of cesium-137 through the detrital food chain in a forest ecosystem in Japan
Radionuclides, including (137)Cs, were released from the disabled Fukushima Daiichi Nuclear Power Plant and had been deposited broadly over forested areas of north-eastern Honshu Island, Japan. In the forest, (137)Cs was highly concentrated on leaf litters deposited in autumn 2010, before the accident. Monitoring of the distribution of (137)Cs among functional groups clearly showed the role of ...
