A mechanical device for supporting and attaching at least one ionizing radiation detection probe. For each detection probe it includes one probe-holder ending in a collimator-holder able to support a collimator intended to delimit a field of observation of the detection probe, and an attachment device intended to be attached to a glove port of a glove box, where the probe-holder, or each probe-holder, cooperates with the said attachment device.

A radiological characterization device comprising at least one collimated radiological measuring probe, a sensitive end of which is placed in an exchangeable collimator having an opening and a field of observation. The collimator is carried by a collimator holder, the assembly consisting of collimator and collimator holder being inserted in a stack between two shielding screens, the shielding screens being exchangeable so as to adjust the thickness thereof, the assembly consisting of collimator and collimator holder and the shielding screens providing protection for the probe vis-&#xe0;-vis parasitic ionizing radiation coming from ionizing radiation sources situated outside the field of observation of the collimator.

Radiological characterization device protected against parasitic ionizing radiation sources

The invention relates to a device limiting the appearance of decoding artefacts for a gamma camera with a coded mask comprising a gamma radiation detector () opposite the coded mask () and having a field of view with an area partially coded () by the coded mask (). It comprises a recessed part (), which is opaque to the gamma radiation, to be arranged opposite the detector () with respect to the coded mask (), with said recessed part () obscuring the partially coded area () of the field of view for the detector ().
