ASTM E1297-08(2013) PDF

Scope: 5.1 Refer to Practice E261 for a general discussion of the determination of decay rates, reaction rates, and neutron fluence rates with threshold detectors (1-29).³ Refer to Practice E1006, Practice E185 and Guide E1018 for the use and application of results obtained by this test method.(34-36)

5.2 The half-life of ^93mNb is 5730 ?? 220 days (30) and has a K X-ray emission probability of 0.1099 ?? 0.0025 per decay (30). The K_?? and K_?? X-rays of niobium are at 16.5213???16.152 and 18.618???18.953 keV, respectively. The recommended ⁹³Nb (n,n???)^93mNb cross section comes from the IRDF-90 cross section compendium (31), was drawn from the RRDF-98 c......
