WebFor other energy ranges, see Wang, p 912. [5] Values are from Y. Wang (reference). Another rule-of-thumb is that the half-value range is approximately 1/7 of the maximum range but may vary between 1/5 and 1/10 (depending on beta energy and absorber density). [6] The mass absorption coefficient also depends on the energy of the radiation. WebAlthough the method is approved for alpha emitters and mid-to-high energy beta emitters, there are some limitations. Alpha emitters and mid-range energy beta emitters will be significantly attenuated in samples containing dissolved or suspended solids. Thus sample self-absorption calibrations are necessary to minimize bias for these radionuclides. razor knife and blade knife combo
