N42.12-1980 - American National Standard Calibration and Usage of Sodium Iodide Detector Systems

Description: This standard establishes methods for performance testing, calibration, and usage of sodium iodide detector systems for the measurement of gamma-ray emission rates of radionuclides; the assay for radioactivity; and the determination of gamma-ray energies. It covers both energy calibration and efficiency calibration. The following three techniques are considered: total spectrum counting; single-channel analyzer counting; and multichannel analyzer counting.
