Embodiment Construction

[0045] figure 1 A radiographic inspection system 1 , in particular such an X-ray scanning system for detecting foreign bodies and contamination in products, eg in the food and pharmaceutical industry, is schematically shown. An inspection or scanning system 1 of this type has a fixed radiation source (not visible in the drawing) and a fixed linear detector array (not visible in the drawing) arranged in a cabinet-like enclosure 2, said cabinet The enclosure 2 has an inlet 3 and an outlet 4 (not visible). As can be seen in this figure, the inlet 3 is closed by a radiation protection curtain 5 . Usually, the outlet 4 is likewise closed by another radiation protection curtain 5 of the same type. The inspection system 1 further comprises a conveyor belt 6 for transporting the inspected item 7 through the inlet 3, through the space within the enclosure 2 between the radiation source and the detector array as the item 7 passes through the inspection system 1 , Go out through exit ...

Abstract

A radiation-shielding curtain (20) of the kind used at the conveyor entrance and exit openings of a radiographic inspection system or irradiation system is composed of a large number of straight, slender, vertically suspended rods (21) which have a convex outwardly rounded cross-sectional profile and a smooth low friction surface.

Description

technical field [0001] The invention relates to the field of in-line radiation equipment, ie systems for exposing objects to radiation, for example for the purpose of inspection with transmitted or reflected radiation or for germicidal irradiation. X-ray scanning systems for detecting foreign objects and contaminants in food and pharmaceuticals are known in the state of the art. For safety reasons, radiation in this type of scanning system or irradiation system is contained in a cabinet-like enclosure with inlet and outlet and a conveyor belt for the items to be removed as they pass through the inspection or irradiation system. Items inspected or irradiated are transported through the inlet, through the inspection or irradiation area located within the enclosure, and out through the outlet. In particular, the invention relates to radiation protection curtains arranged at the entrance and exit of said system. A common example of such an X-ray system with conveyor belts and pr...
