| Summary: | This work evaluates the efficiency calibrating of HpGe detector coupled with Canberra GC3018 with Genie
2000 software and Ortec GEM25-76-XLB-C with Gamma Vision software; available at Neutron activation analysis
laboratory in Malaysian Nuclear Agency (NM). The efficiency calibration curve was constructed from measurement of
an IAEA, standard gamma–point sources set composed by 214Am, 57Co, 133Ba, 152Eu, 137Cs and 60Co. The efficiency
calibrations were performed for three different geometries: 5, 10 and 15 cm distances from the end cap detector. The
polynomial parameters functions were simulated through a computer program, MATLAB in order to find an accurate fit
to the experimental data points. The efficiency equation was established from the known fitted parameters which allow
for the efficiency evaluation at particular energy of interest. The study shows that significant deviations in the efficiency,
depending on the source-detector distance and photon energy |
