A Study of Antrasen Organic Material (C14H10) in a Scintillation Detector

Abstract

A scintillation detector that uses antrasen organic material (C14H10) as its scintillator to detect beta radiation has successfully been built. This research is aimed at proving the ability of antrasen (C14H10) as an organic material that can detect beta radiation from sources of know activities. The other purpose is to make a scintillator of optimum thickness that produces maximum radiation count and efficiency. The scintillator was made by putting the antrasen (C14H10) under a 120 kN/cm2 Pressure. Thickness of the resulting scintillator varies from 1 mm to 5 mm with 0.5 mm variation. Test results indicate that those scintillators are capable of detecting beta radiation. This is evident in the sheer number of count ratio between background and source radiation detected. Optimum thickness for Cs- 137 is 2 mm with an efficiency of 92.1%. Results also indicate that the antrasen (C14H10) improves the counts produced by the NaI(Tl) organic detector by up to 2.9% through 67.3%.
