To prevent radiation leaking from shielding measures from reaching specific areas. [Solution] The electron beam irradiation device (100) comprises an electron beam generator (4) that generates an electron beam, a transport cylinder (5) that transports the paper (P) so that it passes through the irradiation area (IR) irradiated by the electron beam by holding and rotating a part of the paper (P) to be irradiated by the electron beam, a shielding structure (8) provided around the irradiation area (IR) in the transport cylinder (5) to shield the radiation, and a guide structure (10) that guides the radiation leaked from the end of the shielding structure (8) in a specified direction.

A radiation-absorbent shield shaped to conform to and enshroud the x-ray tube housing of a C-arm in order to protect medical personnel from radiation leaking through the x-ray tube housing. The shield is attached to the x-ray tube housing such that it moves with the tube housing and provides protection no matter the orientation of the C-arm.

The application relates to a clamping antenna asynchronous uplink and downlink transmission method, which is suitable for a clamping antenna system equipped with a single waveguide or multiple waveguides, aims to solve the problem of inter-antenna radiation leakage during uplink signal transmission, and realizes near full-duplex collaborative communication by asynchronously and independently controlling the working modes of the waveguides without changing the hardware. The application is realized through the following steps: firstly, a base station assembles working modes for each waveguide asynchronously according to global and local state information, and sends clamping antenna activation instructions to each waveguide; secondly, each waveguide reconstructs the clamping antenna according to the instructions, only activates a single designated antenna in the uplink mode, and can activate a single or multiple antennas in the downlink mode; finally, the base station globally monitors the transmission state, and starts a new round of scheduling cycle when the conditions are met.
