A PLASTIC SACHET DOSIMETER CONTAINING LITHIUM FLUORIDE POWDER FOR SURFACE AND FINGER-TIP DOSIMETRY

摘要

A dosimeter is described, consisting of 30 mg of thermoluminescent lithium fluoride powder contained in a plastic sachet. Measurements of its sensitivity for photons and beta rays are presented and discussed. It is shown to provide a convenient, accurate and reliable method of measuring directly the finger-tip radiation dose of workers handling radioactive materials, surface doses from such materials and doses in general operational and experimental work.
