Abstract

This report describes the detection and dosimetry of gamma ray emitted from Thallium-201 ((TI)-T-201) and Technetium-99m(Tc-99m) based on chemiluminescence technique. H2O2 produced by two gamma emitter radioisotopes of (TI)-T-201 and Tc-99m were quantitatively measured by chemiluminescence method. Upon producing H2O2 in a luminol alkaline solution, in the presence of diperiodatocuprate, as catalyst a chemical reaction was accrued and consequently the emitted light was measured. The determined H2O2 concentration was correlated with the gamma ray detection and dosimetry. The sensitivity of chemiluminescence technique for (TI)-T-201 and Tc-99m dosimetry was determined to be 0.20 and 0.08 MBq/l (Mega Becquerel per liter) respectively (R.S.D. = 5, N=3). The plotted calibration curves showed detection limits of 3.24 and 1.76 MBq/l for (TI)-T-201 and Tc-99m, respectively. (C) 2010 Elsevier Ltd. All rights reserved.
