Abstract: A screen made of radiation shielding material for protecting an operator from ionizing radiation, includes: (i) a lower part equipped with a front wall made of radiation shielding material, having an upper border; (ii) an upper part equipped with a front wall made of a radiation shielding material, at least one part of which is transparent, which front wall includes a lower border; and (iii) at least one passage for the arms of the operator. The front walls of the upper part and of the lower part are separable from each other, the upper part being borne by supporting elements allowing the screen to be reversibly maneuvered either into an active radiation shielding position in which the upper and lower borders are juxtaposed, or into a retracted position in which the upper and lower borders are separated from each other, in order to free a space above the lower part.

Abstract: A protection device to be fitted onto a syringe (2) used for injecting radioactive material(s). The radiation protection device includes a tubular radiation protection housing (1) that includes an outer tubular part (15), which constitutes at least a portion of the outer surface (11) thereof, and which is made of an elastomeric material. The tubular portion (15) also includes an annular constrictive portion (20) including a resiliently deformable inner surface that is used to apply a compressive force around the cylindrical body (3) of the inserted syringe (2).

Abstract: A sterile screen cover made of radioprotective material has an L-shaped horizontal section, including a front wall associated with a side wall. The front wall has two orifices through which the arms of the operator can pass, a first orifice being located close to the angle of the screen, the second being located on the free edge of the front wall. The sterile cover is a single part that includes at least one internal “panel” and one “external panel” joined together by a joining region, the panels intended to cover, respectively, at least the internal and external faces of the front wall and at least part of the height of its free edge. The joining region has an indentation shaped to match the border of the second passage orifice; these inner and outer panels are each provided with an opening intended to be placed in front of the first passage orifice.

Abstract: A method of measuring the activity of a radioisotope (3) placed in an ionisation chamber (1) consists in:—determining the energy spectrum of the radiation emitted by the radioisotope;—automatically comparing the energy spectrum with a set of pre-recorded or pre-programmed radioisotope energy spectra in such a way as to identify the radioisotope present;—subsequently, automatically directing the calibration coefficient corresponding to the radioisotope present to the electronic measuring elements in order to obtain the appropriate activity measurement. The invention provides a totally automatic activity measurement. Moreover, the invention also relates to an activity meter with radioisotope recognition which is used to obtain an automatic activity measurement. The device employs one or more scintillation—or semi-conductor-type radiation detectors (10) for determining the energy spectrum of the radioisotope present.
