Testing of CaSO-4:Dy in Teflon Discs as a Thermoluminescent Dosimetry Material for Personal Monitoring of Uranium Mine and Mill Workers.

摘要

Some studies of the spectroscopic and thermoluminescent properties of CaSO sub 4 :Dy are discussed. Measurements were also made in the field. Exposures measured using TLD, film and spot monitoring were in agreement, and these observations, together with measurements made at various heights above the ore stockpile have shown that CaSO sub 4 :Dy in teflon discs, shielded by 2mm of copper, give a reliable measure of the exposure at the appropriate position on the wearer's body. This exposure may then be converted into the dose equivalent for the whole body. (Atomindex citation 12:622781)
