Weiyu He. Determination of nuclear purity and activity of medical radionuclides with γ spectrometers[J]. Nuclear techniques, 1990, 13(12): 760-764.DOI:
The methed of efficiency calibration for a HpG e detector is described in detail. An efficiency curve of spot source was determined for γ-ray energy region of 40-1400keV. For convenience of routine measurement
an efficiency curve of volume source was obtained in the same energy region with a total uncertainty of ± 3%.
The satisfactory applications of this method to analysing medical radionuclides
201
Tl and
