ASTM E2971 – Standard Test Method for Determination of Effective Boron-10 Areal Density in AluminumNeutron Absorbers using Neutron Attenuation Measurements
1.1”This test method is intended for quantitative determination of effective boron-10 (10B) areal density (mass per area of 10B, usually measured in grams-10B/cm² ) in aluminum neutron absorbers. The attenuation of a thermal neutron beam transmitted through an aluminum neutron absorber is compared to attenuation values for calibration standards allowing determination of the effective 10B areal density. This test is typically performed in a laboratory setting. This method is valid only under the following conditions:
1.1.1”The absorber contains 10B in an aluminum or aluminum alloy matrix.
