Organization: ASTM
Publication Date: 1 June 2013
Status: inactive
Page Count: 5
ICS Code (Fissile materials and nuclear fuel technology): 27.120.30
ICS Code (Radiation measurements): 17.240
scope:

This test method covers procedures for measuring reaction rates by assaying a fission product (F.P.) from the fission reaction 237Np(n,f)F.P.

The reaction is useful for measuring neutrons with energies from approximately 0.7 to 6 MeV and for irradiation times up to 30 to 40 years.

Equivalent fission neutron fluence rates as defined in Practice E261 can be determined.

Detailed procedures for other fast-neutron detectors are referenced in Practice E261.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.
