INFLUENCE OF MINERAL COMPOSITION ON THE THERMOLUMINESCENCE OF IRRADIATED FOODSTUFFS

摘要

In order to demonstrate an irradiation treatment, the application of acetic acid and ethanol in the isolation procedure seems to be more suitable than that of hydrochloric acid and acetone: the crystal structure of the mineral fraction is less damaged, and more intensive TL signal is detected. Concerning the TL response, among the components of silicate minerals, feldspar may be the dominant part responsible for TL, but TL sensitivity may depend on the type of the feldspar (SANDERSON, 1990).
