1、Designation: E1005 10Standard Test Method forApplication and Analysis of Radiometric Monitors forReactor Vessel Surveillance, E 706(IIIA)1This standard is issued under the fixed designation E1005; the number immediately following the designation indicates the year oforiginal adoption or, in the case

2、 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 method describes general procedures for measuringthe specific activities of radioactive

3、 nuclides produced inradiometric monitors (RMs) by nuclear reactions inducedduring surveillance exposures for reactor vessels and supportstructures. More detailed procedures for individual RMs areprovided in separate standards identified in 2.1 and in Refs 11,24-27. The measurement results can be us

4、ed to define corre-sponding neutron induced reaction rates that can in turn beused to characterize the irradiation environment of the reactorvessel and support structure. The principal measurement tech-nique is high resolution gamma-ray spectrometry, althoughX-ray photon spectrometry and Beta partic

5、le counting are usedto a lesser degree for specific RMs (1-29).21.1.1 The measurement procedures include corrections fordetector background radiation, random and true coincidencesumming losses, differences in geometry between calibrationsource standards and the RMs, self absorption of radiation byth

6、e RM, other absorption effects, radioactive decay corrections,and burn out of the nuclide of interest (1-10, 12-22).1.1.2 Specific activities are calculated by taking into ac-count the time duration of the count, the elapsed time betweenstart of count and the end of the irradiation, the half life, t

7、hemass of the target nuclide in the RM, and the branchingintensities of the radiation of interest. Using the appropriatehalf life and known conditions of the irradiation, the specificactivities may be converted into corresponding reaction rates(24-30).1.1.3 Procedures for calculation of reaction rat

8、es from theradioactivity measurements and the irradiation power timehistory are included. A reaction rate can be converted toneutron fluence rate and fluence using the appropriate integralcross section and effective irradiation time values, and, withother reaction rates can be used to define the neu

9、tron spectrumthrough the use of suitable computer programs (24-30).1.1.4 The use of benchmark neutron fields for calibration ofRMs can reduce significantly or eliminate systematic errorssince many parameters, and their respective uncertainties,required for calculation of absolute reaction rates are

10、commonto both the benchmark and test measurements and therefore areself canceling. The benchmark equivalent fluence rates, for theenvironment tested, can be calculated from a direct ratio of themeasured saturated activities in the two environments and thecertified benchmark fluence rate (24-30).1.2
