2、ption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method describes general procedures for measuring the specifi
3、c activities of radioactive nuclides produced inradiometric monitors (RMs) by nuclear reactions induced during surveillance exposures for reactor vessels and support structures.More detailed procedures for individual RMs are provided in separate standards identified in 2.1 and in Refs 1, (2-1-5.).2
4、Themeasurement results can be used to define corresponding neutron induced reaction rates that can in turn be used to characterizethe irradiation environment of the reactor vessel and support structure. The principal measurement technique is high resolutiongamma-ray spectrometry, although X-ray phot
5、on spectrometry and Beta particle counting are used to a lesser degree for specificRMs (6-1-29).1.1.1 The measurement procedures include corrections for detector background radiation, random and true coincidencesumming losses, differences in geometry between calibration source standards and the RMs,
6、 self absorption of radiation by the RM,other absorption effects, radioactive decay corrections, and burn out of the nuclide of interest (6-1526, 16-26).1.1.2 Specific activities are calculated by taking into account the time duration of the count, the elapsed time between start ofcount and the end
7、of the irradiation, the half life, the mass of the target nuclide in the RM, and the branching intensities of theradiation of interest. Using the appropriate half life and known conditions of the irradiation, the specific activities may be convertedinto corresponding reaction rates (2-530,28-30).1.1
8、.3 Procedures for calculation of reaction rates from the radioactivity measurements and the irradiation power time historyare included. A reaction rate can be converted to neutron fluence rate and fluence using the appropriate integral cross section andeffective irradiation time values, and, with ot
9、her reaction rates can be used to define the neutron spectrum through the use ofsuitable computer programs (2-530,28-30).1.1.4 The use of benchmark neutron fields for calibration of RMs can reduce significantly or eliminate systematic errors sincemany parameters, and their respective uncertainties,
10、required for calculation of absolute reaction rates are common to both thebenchmark and test measurements and therefore are self canceling. The benchmark equivalent fluence rates, for the environmenttested, can be calculated from a direct ratio of the measured saturated activities in the two environ
11、ments and the certifiedbenchmark fluence rate (2-530,28-30).1.2 This method is intended to be used in conjunction with ASTM Guide E844.
