Abstract

The organic scintillator detectors made of naphtalene (C101-10) had been fabricated and tested. For this purpose the naphtalen powder are pressed at 150 kN/cm . The diameter of pressed powder is 5 cm and the density thickRess of the scintillator are variated from 107.14 mg/cm to 801.50 mg/cm . From test result, it's found that the efficiency is (6.7 ± 0.2)%. This efficiency achieved at the density thickness of scintillator 687.00 mg/cm for Cs-137. While for Sr-90 the efficiency is (59.3 ±20.3)% at the density thickness of scintillator 286.25 mg/cm , for Co-60 the efficiency is (2.5 ± 2.1)% at the density thickness of scintillator 157.56 mg/cm and for Eu-152 the efficiency is (7.4 ± 0.7)%2 at the density thickness of scintillator 138.44 mg/cm . For point sources of Cs-137, Sr-90, Co-90 and Eu-152, the optimum thickness density is 286.25 mg/cm iv This document is Undip Institutional Repository Collection.
