“…This apparatus was calibrated using a standard source standardized with a gamma-ray spectrometry method for 137 Cs, 60 Co, 133 Ba, and 99m Tc radionuclides, while 131 I and 18 F radionuclides were standardized absolutely with a  coincidence method; however, 125 I is measured with an absolute photonphoton coincidence counting method [10,11].…”

The absolute standardization of 32 P radioactive sources employed to calibrate nuclear medicine instruments has been conducted at PTKMR-BATAN. We deemed this activity to be necessary since 32 P used in the nuclear medicine fields has a short half-life, and in order to obtain a result of quality measurement, it requires a special treatment. Moreover, in Indonesia, the use of nuclear medicine techniques has developed rapidly. We prepared all the radioactive sources with a gravimetric method by using a KERN ABT 220-5DM semi-micro type scale, traceable to the International Unit System. We conducted the 32 P standardization by employing a (PS)-coincidence method with 60 Co as a tracer; meanwhile, we conducted the impurity measurement by employing a beta spectrometer system. The result of 32 P absolute measurement was 380.05 Bq/mg with a 0.68-percent range uncertainty, with a k=2 coverage factor. This value was used to calibrate a "Capintec CRC-7BT" dose calibrator that was a secondary standard instrument in PTKMR-BATAN. The results showed us that the calibration factor of the "Capintec CRC-7BT" dose calibrator was 1.12 with a 4.7-percent uncertainty.Journal homepage: http://aij.batan.go.id

“…Pommé et al [6] described and used seven techniques for 125 I solution standardisation. If we limit only to photon detection, two methods most widely used are photon-photon coincidence counting and the sum peak coincidence method [7][8][9][10][11][12][13]. In photon-photon coincidence counting method two NaI(Tl) detectors are used to identify coincidence events between X-rays originating from 125 I EC and gamma-rays or X-rays 58 originating from the 125 Te de-excitation (isomeric transition).…”
