Abstract
This paper presents some of the results obtained from a study of thermoluminescence (TL) in γ-ray irradiated normal paraffins above room temperature. The samples used were commercial paraffins of which carbon number was ranging from 21 to 40. After irradiation, samples were warmed from room temperature to above melting points.
A characteristic sharp TL peaks having very narrow half-line width of around 0.5°C were observed for all samples. The sharp peaks were stable and remained constant in spite of varying with heating rate ranging from 1 to 15°C min-1. Comparison TL glow curve with DSC curve leads to the conclusion that the sharp glow peaks are in good agreement with the solid state transition points.
From these facts, it seems expected that normal paraffins are available as a standard sample to check a temperature calibration for TL experiments of organic materials.
