Abstract
A reference source with the granular active portion was made using 152,154Eu(III) loaded tin tungstate material. Batch equilibration method was used to investigate the interaction of 152,154Eu(III) radiotracer (10−4 M) in acid solutions on tin(IV) tungstate gel matrix. The sorption behavior of 152,154Eu(III) showed high affinity towards tin(IV) tungstate gel matrix at low pH values. Tin tungstate gel matrix was loaded with 152,154Eu from batch at pH 3. Standardization of the source was done spectroscopically with reference to primary certified set of radioactive sources and with the aid of HPGe detector. Random and true coincidence summing was carried out by following-up coincidence in 152Eu and possible interference between γ lines of 152Eu and 154Eu. The relation between the grain size and the activity of samples was studied. Correction factor for capsule attenuation was applied.
