Gamma Dose Rate Measurement and Dose Rate Calculation for Sensitive Organs in the Vicinity of Hot Springs in Kerman Province
Introduction: All of the people worldwide are exposed to low levels of radiation. Cancer induction and genetic disorders are among the hazards of low level exposure. In some cases, radiation close to hot springs is higher than normal areas due to a high concentration and the decay products of Ra-226. Given the use of hot springs by the general public because of their therapeutic p...
متن کاملPerformance of Sife - Eldeen dosimeter over broad absorbed dose and dose rate ranges of γ – radiation and at different temperatures
Background: Results are presented on some dosimetric characteristics of Sife – Eldeen dosimeter based on the radiation induced conductivity (RIC) of 3.5 M aqueous urea solutions. The studied characteristics were the response (RIC) of Sife – Eldeen dosimeter in broad ranges of absorbed dose, dose rates and at different irradiation temperature. Materials and Methods: Kent EIL5007 conductivity met...
متن کاملCCRI supplementary comparison of standards for absorbed dose to water in 60 Co gamma radiation at radiation processing dose levels
Six national standards for absorbed dose to water in Co gamma radiation at the dose levels used in radiation processing have been compared over the range from 5 to 30 kGy using the alanine dosimeters of the NIST and the NPL as the transfer dosimeters. The standards are in agreement at the level of around 0.5%, which is significantly smaller than the stated standard uncertainties. r 2006 Elsevie...
متن کاملThe Graphite Calorimeter as a Standard of Absorbed Dose for Cobalt-60 Gamma Radiation
Absorbed dose to water in a cobalt-60 gamma-ray beam has been determined using a thick-walled graphite ionization chamber. The chamber was calibrated in a graphite phantom against a graphite calorimeter, and the graphite calibration factor was converted to a water calibration factor using published energy absorption coefficient ratios and a measured replacement factor. Comparisons between the g...
