1.1 This test method describes the nondestructive assay (NDA) of plutonium, tritium, and 241<\/sup> Am using heat flow calorimetry. For plutonium the typical range of applicability corresponds to ~1 g to ~2000 g quantities while for tritium the typical range extends from ~0.001 g to~ 10 g. This test method can be applied to materials in a wide range of container sizes up to 50 L. It has been used routinely to assay items whose thermal power ranges from 0.001 W to 135 W.<\/p>\n

1.2 This test method requires knowledge of the relative abundances of the plutonium isotopes and the 241<\/sup> Am\/Pu mass ratio to determine the total plutonium mass.<\/p>\n

1.3 This test method provides a direct measure of tritium content.<\/p>\n

1.4 This test method provides a measure of 241<\/sup> Am either as a single isotope or mixed with plutonium.<\/p>\n

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

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.<\/span><\/p>\n
