Standard Test Method for Oxygen Content Using a 14-MeV Neutron Activation and Direct-Counting Technique

Organization: ASTM
Publication Date: 1 January 2016
Status: active
Page Count: 8
ICS Code (Fissile materials and nuclear fuel technology): 27.120.30
scope:

This test method covers the measurement of oxygen concentration in almost any matrix by using a 14-MeV neutron activation and direct-counting technique. Essentially, the same system may be used to determine oxygen concentrations ranging from under 10 μg/g to over 500 mg/g, depending on the sample size and available 14-MeV neutron fluence rates.

NOTE 1-The range of analysis may be extended by using higher neutron fluence rates, larger samples, and higher counting efficiency detectors.

This test method may be used on either solid or liquid samples, provided that they can be made to conform in size, shape, and macroscopic density during irradiation and counting to a standard sample of known oxygen content. Several variants of this method have been described in the technical literature. A monograph is available which provides a comprehensive description of the principles of activation analysis using a neutron generator (1).2

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. Specific precautions are given in Section 8.
