Measurement of Cesium-137 and Cobalt-60 Gamma Radiation With a Pressure Ionization Chamber
The characteristics of the pressure ionization chamber at t he National Bureau of Standards have been studied for the gamma radiation from a cesium-137 sou rce (0.6614 Mev) and from a cobalt-60 source (1.1715 and 1.3316 Mev). The dosage rates produced in air by these sources were measured with this chamber with an accuracy of about 2 percent. Dosage rates obtained with an extrapolation chamber ...

متن کاملAssessment of radiation exposure from cesium-137 contaminated roads for epidemiological studies in Seoul, Korea
OBJECTIVES We aimed to assess the radiation exposure for epidemiologic investigation in residents exposed to radiation from roads that were accidentally found to be contaminated with radioactive cesium-137 ((137)Cs) in Seoul. METHODS Using information regarding the frequency and duration of passing via the (137)Cs contaminated roads or residing/working near the roads from the questionnaires t...
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...
