Organization: ASTM International
Publication Date: 10 June 2002
Status: inactive
Page Count: 3
ICS Code (Radiation measurements): 17.240
ICS Code (Fissile materials and nuclear fuel technology): 27.120.30
scope:

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

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).

1.3 With suitable techniques fission-neutron fluence rates densities above 107 cm2s 1 can be determined.

1.4 Detailed procedures for other fast-neutron detectors are referenced in Practice E 261.

1.5 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.
