Determination of Self-absorption Correction Factors of Some Algae Samples: An Experimental study

Abstract

The purpose of this study to examine experimentally self-absorption correction factors (SACFs) of some algae samples using gamma-ray spectrometry. Various algae samples were collected from Boğaçay in Antalya, Turkey. Collected algae samples were dried, and masses of the samples were calculated. Then densities of the samples were calculated. Each of algaes was counted with and without point sources which are 22Na, 60Co, 133Ba, and 137Cs about 1000 seconds using high purity germanium detector. The SACFs of algae samples were calculated between 80 keV and 1332 keV gamma-ray energies. As a result, SACFs of studied algae samples generally reduce as gamma-ray energy enhances. SACFs of some algae samples are nearly steady because of the densities and elemental contents of the studied algaes.
