ASTM C1030-95 用γ射线测试钚同位素成分的标准试验方法

1.1 This test method is applicable to the determination of isotopic abundances in isotopically homogeneous Pu-bearing materials. This test method may be applicable to other plutonium-bearing materials, some of which may require modifications to the described test method. 1.2 The procedure is applicable to sample sizes ranging from a few tenths of a gram up to the maximum sample weight allowed by criticality limits. 1.3 Because 242 Pu has no useful gamma-ray signature, its isotopic abundance is not determined. Isotopic correlation techniques may be used to estimate its relative abundance (Refs 1, 2). 1.4 This test method has been demonstrated in routine use for isotopic abundances ranging from 94 to 70% 239 Pu. This test method has also been employed for isotopic abundances outside this range. 1.5 The values stated in SI units are to be regarded as the standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM C1118-89(2000) 波长色散X射线荧光(XRF)系统用部件选择的标准指南

1.1 This guide describes the components for a wavelength-dispersive X-ray fluorescence system for materials analysis. This guide can be used as a reference in the apparatus section of test methods for wavelength-dispersive X-ray fluorescence (XRF) analyses of nuclear materials. 1.2 The components recommended include X-ray detectors, signal processing electronics, excitation sources, and dispersing crystals. 1.3 Detailed data analysis procedures are not described or recommended, as they may be unique to a particular analysis problem. Some applications may require the use of complex computer software during data reduction to correct for matrix effects. 1.4 The values stated in SI units are to be regarded as the standard. 1.5 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Sets forth the principles for collecting representative samples and prescribes acceptable methods and materials for gas and particle sampling (collection of the samples, and not their measurement), limited to sampling in installations where work with radioactive materials is conducted, including sampling effluent gases prior to, or at, the point of release to the atmosphere, and with the primary emphasis on the need to protect the radiation worker. Does not consider application of various collectors to specific problems.
