Measurement of photon-energy albedo from stratified shielding materials.
In the conventional method of measuring photon-energy albedo using a scintillation detector coupled with a multichannel analyzer, tedious efficiency correction by the inverse matrix method was needed. The indigenously designed proportional-response photon counter, with its detection efficiency proportional to energy of incident photons, was used in the present investigation. Use of the proportional-response photon counter makes the measurement straightforward and more accurate. Measurements of energy albedo from stratified layers of aluminum, iron, lead, and concrete using 662-keV and 1250-keV photon energies are reported.
