Abstract
The article presents the results of the work on verification of the constant support in the modeling of the processes of transfer of gamma-quanta in the RASTAS program based on the comparison of the calculated transfer characteristics obtained within the framework of precision codes using modern constant support. Verification was carried out in the justification of calculations of the dose rate of unfiltered photon radiation from the specified nuclides-sources of photon radiation. The data of the RASTAS program library (1280 nuclides) are based on the estimates of ENDF/B-VII.1 and partially on the BIPM-5 data. The work considered several sources of data on the yields of gamma quanta during radioactive decay: ICRP-107 (2008), SCALE6.2.4 (2012), BIPM-5 (2004–2016). To verify the initial data of gamma radiation sources and the procedure for handling these data, calculations of gamma constants (i. e., the effective equivalent dose power of point sources at a distance of 1 m without taking into account scattering and absorption (i. e., in a vacuum) for radioactive nuclides important for the processes of plutonium processing and spent nuclear fuel management From the analysis of the comparison, it was found that the discrepancy between the gamma constants for the considered fission product nuclides does not exceed 3 %. For actinides, where there is significant low-energy photon radiation, the divergence does not exceed 15 %.
