A phosphor for a thermoluminescent radiation dosimeter, which is composed primarily of beryllium oxide doped with at least one activator selected from the group consisting of lithium, sodium, potassium, silicon, germanium, tin, zinc, cadmium, aluminum, thallium, cadmium and ytterbium, and which is especially adapted for measuring the dose absorbed by a tissue as its effective atomic number is approximately the same as that of the tissue, and has an excellent sensitivity and retention of radiation energy absorbed. |
