| Popis: | Quantum mechanics consideration, supported by a concrete example, yielded standard sources of di rect volt age mea sured by frequency (which is the most ac cu rate measur able phys-ical quantity) and extremely sensitive instrument for measuring magnetic induction SQUID (which is an ac ro nym based on the term Supercon duct ing Quan tum Inter fer ence Device). The pos sibility of these mea sure ments is based on the Josephson junc tion. In this paper, the in flu ence of gamma ra diation on the mea sure ment un cer tainty Type A, of a com mercial Josephson compound, is investi gated. The conclu sion is that both dy namic gamma radiation and the dose of gamma ra di ation, un der the con ditions of the ex per iment, have a neg ligible ef-fect on the mea sure ment uncer tainty of the Josephson junc tion. Based on the ob tained re sult, it was con cluded that in the primary metrological con di tions, the mea sure ment un cer tainty type A of the Josephson junc tion is neg ligible, i. e., that the secondary cosmic radiation does not af fect the stan dard of the DC volt age source. © 2021, Vinca Inst Nuclear Sci.
