Comparison of Gamma-Ray Nondestructive Assay Measurement Techniques
ثبت نشده
چکیده
Several techniques based on gamma-ray measurements are commonly available for Nondestructive Assay (NDA) of radionuclides including Special Nuclear Material, including plutonium and uranium. The techniques and associated instruments discussed here are referred to as : "ISO-CART", "QED", "SGS" and "TGS"; some include shielded chambers for the lowest activity measurements. This technical note compares the measurement characteristics and the range of samples for these techniques. Not all aspects of the technology are covered, but this is a guide to NDA users and those with a general knowledge of gamma-ray measurement technology in the selection of a system for their use.

متن کاملSurface Hardness Measurment and Microstructural Characterisation of Steel by X-Ray Diffraction Profile Analysis
An X-ray diffraction line will broaden considerably when steels change into martensitic structure on quenching. The results presented in this paper show that X-ray diffraction technique can be employed for a rapid and nondestructive measurement of hardness of hardened steel. Measurement on various quenched and tempered steels showed that the breadth of its diffraction peak increased with increa...
متن کاملComparison between Amperometric and Chemiluminescence methods in detection and dosimetry of cobalt-60 gamma ray emission
Background: Hydrogen peroxide (H2O2), produced by gamma ray irradiation to watery solution, was used as an analytical parameter for dosimetry of cobalt-60 (60Co) radiation. Materials and Methods: Detection of the produced H2O2 was carried out using two methods: an amperometric biosensor fabricated by immobilization of anthraquinone 2-carboxylic acid modified horseradish peroxidase on glassy car...
