dosimetric system for ionizing radiation

摘要

The invention relates to a system dosimetric to ionising radiation comprising at least: / p & & p & a dosimeter constitutes a protective sheath 1 and a support 3 containing the sensitive elements 24, 25, such sensors, which are sensitive to gamma radiation and to thermal neutrons or "slow" and a semi - conductor 27 which is sensitive to the fast neutrons, on the one hand, and / p & & p & - a reader comprises a frame 30, 31 and a reception mechanism 34, 35 of the dosimeter, relates to a source of excitation 70 is ultra - violet radiation and of a measuring device 64 of the radiation issued by the sensors and of a device 66 for measuring the electrical magnitudes linked to the device, a semi - driver of the other hand. / p & & p & the support of the dosimeter is provided with a folding 9 and is constituted by a body 10 containing the elements sensitive locked by a plate 28, comprising a end a means of a section 18 and the other end a snap-fastening means 11 on the carton. / p & & p & the frame of the reader is constituted of two parts, one a cap 31 supporting the source 63 and the measuring devices 64, 66, the other a base 30 which ensures the guidance of the receiving mechanism 34, 35, said mechanism comprising a first means 34 in order to ensure the opening of the dosimeter, the locking of the carton and the transport of the assembly (the body and the outer carton) in the measuring position, in combination with a drive means 45, a second means 35 ensuring the immobilization of the body.
