In electron beam welding a very intense pencil beam of electrons is driven onto the base metal, to melt it and produce the welding. In the interaction of the beam with the metal, strong bremsstrahlung emission of X-ray is generated. Here the generation is evaluated, and the KERMA in air at 1 m is predicted. Results show that a significant radiation hazard is present and serious radiation protection measures are needed.

电子束焊接中的放射危害评估

在电子束焊接中，非常强烈的笔形电子束被驱动到母材上，使其熔化并产生焊接。在光束与金属的相互作用中，会产生强烈的致辐射X射线。在此评估发电量，并预测空气中1 m处的KERMA。结果表明存在严重的辐射危害，需要采取严格的辐射防护措施。
