This standard also establishes methods for measuring the alpha and beta counting plateau, crosstalk factors, background, alpha and beta efficiency from prepared standards, correction factors for samples whose self-attenuation or mass differs from that of the standard, and calculation of the sample activities together with their random and total uncertainties. Correction for pulse pileup due to high count rate is also discussed. Although many principles articulated in this standard apply to the counting of radionuclides emitting a maximum beta energy below 100 keV as well, the counting of these low-energy beta emitters requires a higher degree of attention to detail in sample preparation, instrument calibration, and measurement correction factors than addressed in this standard. Therefore, this standard is intended for measuring radionuclides with maximum beta energies above 100 keV.ANSI N42.25-1997: American National Standard Calibration and Usage of Alpha/Beta Proportional CountersCalibrationStandardsCalibrationStandards.621.372NjHacINjHaclDOCUMENT9910135783003321ANSI N42.25-19972574262UNINA01418nam0 22003131i 450 UON0029318820231205103930.44590-272-3732-820070423d1988 |0itac50 baengNL|||| 1||||Old and Middle English language studiesa classified bibliography, 1923-1985compiled by Matsuji TajimaAmsterdamPhiladelphiaBenjamins Publishing1988391 p.23 cm.001UON000369462001 Amsterdam Studies in the Theory and History of Linguistic Science.
