Neutron-activation determination of phosphorus and sulfur in molybdenum and tungsten with the help of a beta-spectrometer

摘要: An instrumental variant of the neutron-activation determination phosphorus and sulfur in molybdenum tungsten was developed with help a ..beta..-spectrometer that makes it possible to discriminate participation /sup 99/Mo 187/W radioisotopes overall activity sample. It shown simultaneous P S on basis 32/P radioisotope is feasible if their contents are comparable or not different by more than 1-1.5 orders magnitude, then maximum relative standard deviation 0.15.
