Characterization of Radioactive Waste Drums by Non Destructive Gamma Spectrometry
Assay of the radioactive content of waste drums is important for inventory and waste disposal purposes. The sampling of the drum content is a difficult, time and labor consuming procedure, involving special radiation protection considerations. On the other hand the characterization of waste drums containing radioactivity by measuring the drum as a whole (without opening) offers overall simplici...
متن کاملComparison of Gamma-ray Non-Destructive Assay Measurement Techniques
Several techniques based on gamma-ray measurements are commonly available for both Safeguards measurements and NonDestructive Assay (NDA) of radionuclides including Special Nuclear Material, including plutonium and uranium. The techniques discussed here are referred to as : "ISO-CART", "QED", "SGS" and "TGS"; some include shielded chambers for the lowest activity measurements. This Technical No...
متن کاملOptimization of measurement counting time in Gamma-ray spectrometry of soil samples
The method of optimal measurement counting time in Gamma spectrometry for soil samples was studied. Gamma spectrometry was done based on minimum detectable activity using the HPGe- p type with efficiency of 30% and FWHM 1.7keV (for 1.33 MeV 60Co). The samples were IAEA-RG Th-1, IAEA-RGU-1 and IAEA-RGK-1 prepared in bottles. The measurements were done for 12 different counting times from 5 min t...
متن کاملFurther Development in Characterization of Radioactive Waste Drums by Non Destructive Gamma Spectrometry at GRR-1
A non destructive technique based on gamma spectrometry and application of the Monte Carlo method for detector efficiency calibration, was used to assay radioactive content waste drums. Exploranium GR-130 miniSPEC portable gamma ray spectrometer was used to externally monitor radioactive waste drums containing ion exchange resin waste from the water demineralization system of GRR-1 open pool-ty...
متن کاملStorage of spent nuclear fuels in nevada.
American Asociation forthe Advancement of Science Science serves its readers as a forum for the presentation and discussion of important issues related to the advancement of science, including the presentation of minority or conflicting points of view, rather than by publishing only material on which a consensus has been reached. Accordingly, all articles published in Science-including editoria...
