Problems solved by technology

[0013] Aside from the fact that this equipment involves counting neutrons rather than beta radiation, it requires a continuous recirculation operation for uninterrupted gas purification and appears complex and expensive, especially the fact that the coating

Embodiment Construction

[0059] figure 1 , 2 and 3 show a portal body pollution detector 1 consisting of a metal parallelepiped compartment 2 comprising a face 3 accessible from the hot zone, with an entrance 4 closed by a rotating barrier 5 for the user. The portal type whole body pollution detector comprises a user exit opposite side 6, closed on the cold area side by a transparent sliding door 7, which door will be opened once the control operation has been carried out in an efficient manner.

[0060] The portal body contamination detector itself comprises, in a known manner, other different control devices which will be described in more detail later in relation to the invention.

[0061] In particular, it comprises, for example, an electronic meter reader 8 placed outside the van stand 2, which allows the user to know the equivalent of the dose he has received while in the hot zone.

[0062] It also includes a horizontal plate 9 which includes a gas cycle proportional counter configured to dete...

Abstract

The invention relates to a device (1) and a method for monitoring the contamination of a user by a radioactive element emitting beta radiation, wherein said device includes a user-passage gantry (2) provided with at least two proportional-counter gas-circulation panels (12) capable of detecting the beta radiation emitted substantially over the height of the user oppositely positioned. The gas circuits of the panels are connected in series, each panel (12) of the proportional counter including a frame (21) in the form of a gas-retention parallelepiped tank defining a cathode, at least five parallel anodes (25) evenly arranged across said frame, a sheet (26) of a conducting polymer entirely attached by bonding means (28) on the entire upper edge of said tank, and a conduction metal protection grid (29) of said panel attached and electrically connected to the frame so as to sandwich said sheet. The gas supply circuit of both panels includes a gas supply valve (16) and a control means (18) for opening / shutting said valve and adapted so as to supply the panels with gas at a predetermined rate.

Description

technical field [0001] The present invention relates to a device for monitoring contamination of users by radioactive elements released by beta radiation, in contaminated areas known as hot areas and in cold areas, less polluted and / or directly in contact with public places The connected zones include a user access door type whole body contamination detector between them. [0002] It also relates to a pollution monitoring method implementing the device. [0003] In addition to the application of the present invention in the field of contamination detection of individuals working in controlled areas and nuclear facilities, a particularly important application is that the detection can monitor radioactive elements released by beta and / or gamma radiation and their presence throughout the body. Background technique [0004] Apparatus or equipment are known for the monitoring of individuals to detect contamination of their body and / or clothing by radioactive products released by...
