ASTM E264-08<\/h3>\n

Historical Standard: Standard Test Method for Measuring Fast-Neutron Reaction Rates by Radioactivation of Nickel<\/h4>\n
\n

ASTM E264<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers procedures for measuring reaction rates by the activation reaction 58<\/sup>Ni(n,p)58<\/sup>Co.<\/p>\n

1.2 This activation reaction is useful for measuring neutrons with energies above approximately 2.1 MeV and for irradiation times up to about 200 days in the absence of high thermal neutron fluence rates (for longer irradiations, see Practice E 261).<\/p>\n

1.3 With suitable techniques fission-neutron fluence rates densities above 107<\/sup> cm\u2212<\/span>2<\/sup>\u00b7<\/span>s\u2212<\/span>1<\/sup> can be determined.<\/p>\n

1.4 Detailed procedures for other fast-neutron detectors are referenced in Practice E 261.<\/p>\n

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/span><\/p>\n

Note<\/span>\u2014The burnup corrections were computed using effective burn-up cross sections of 1650 b for 58<\/sup>Co(n,\u03b3<\/span>) and 1.4E5 b for 58m<\/sup>Co(n,\u03b3<\/span>).<\/p>\n
