1.1 This test method covers procedures measuring reaction rates by the activation reaction 27Al(n,)24Na.
1.2 This activation reaction is useful for measuring neutrons with energies above approximately 6.5 MeV and for irradiation times up to about 2 days (for longer irradiations, see Practice E 261).
1.3 With suitable techniques, fission-neutron fluence rates above 106cm2s1 can be determined.
1.4 Detailed procedures for other fast neutron detectors are referenced in Practice E 261.
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.
