| 英文摘要 | The Min Jiang Testing Reactor (MJTR) is a new irradiation facility for 40Ar/39Ar geochronology. In this study, we systematically evaluated the neutron flux field gradients of the MJTR for irradiation of samples for 40Ar/39Ar dating and yielded an average neutron flux equivalence of 0.21 × 10?4J h?1 over the neutron irradiation process. The vertical and the horizontal gradients are down to 0.68% cm?1 and 0.45% cm?1, respectively, indicating a sufficiently wide neutron flux stabilization field for 40Ar/39Ar sample irradiation. The production rate ratios of interfering reactions are (36Ar/37Ar)Ca: 4.17 ± 0.07 × 10?4, (39Ar/37Ar)Ca: 18.4 ± 3.6 × 10?4, and (40Ar/39Ar)K: 146.5 ± 42.4 × 10?4, within the range of other nuclear reactors worldwide. The J value error can be estimated to be 40Ar/39Ar sample irradiation. ? 2023 The Royal Society of Chemistry. |
