An electron-beam system for curing plastic layers on workpieces has an irradiation chamber, an electron gun, a transport device for conveying workpieces into the irradiation chamber, and a shield as radiation protection. In order to achieve a high throughput of workpieces and effective shielding, provision is made of two or more blocking devices, which can be moved with reference to the transport device and which are arranged in each case as radiation protection on the transport device upstream and downstream of the irradiation chamber, specifically at a spacing in the conveying direction of the transport device in such a way that at least one workpiece fits between two blocking devices.

[ I claim:] [1.] An electron-beam system for curing plastic layers on workpieces, the electron-beam system comprising:an irradiation chamber,an electron gun for generating at least one electron beam in the irradiation chamber,a transport device having a feed section, a processing section and a discharge section for conveying workpieces along a conveying path into, through and out respectively of the irradiation chamber, anda radiation barrier extending alone the feed section and the discharge section, wherein the barrier includes two or more movable blocking devices on each of the feed section and the discharge section and wherein the blocking devices are spaced along the conveying path of the transport device such that a set of one or more workpieces fits between a pair of blocking devices on the feed section and the same set of one or more workpieces fits between a pair of blocking devices on the discharge section, andwherein each blocking device is movable between a closed position which obstructs the conveying path and blocks radiation from the irradiation chamber and an open position which permits passage of a workpiece along the conveying path.
