摘要
A first thermo-fluorescence dosimeter element (1a, b) is sensitive to X-rays and has one portion surrounded by a tin (2) and a second portion by a lead (3) filter. Second and third units have three thermo-fluorescence elements (4-6a, b) sensitive to beta- and gamma-rays with a metal plate beta-ray shield. A fourth unit is sensitive to gamma-rays and is covered with an aluminium filter (9a, b). A fifth unit is sensitive to gamma-rays and thermal neutrons and has a cadmium filter on its front face and a tin filter on its rear. A sixth unit has a similar construction with the tin and cadmium filters reversed. A seventh unit has a thermo-fluorescence element with tin filters (14a, b) on both sides and an eighth unit comprises an indium foil (15).
