100MeV回旋加速器在调试和运行时因束流损失会产生中子和光子等瞬发辐射,束流管道、靶、准直器等元件在束流轰击下会有放射性核素生成,在停机后因这些放射性核素衰变会有残余辐射。在束流损失较严重的情况下,将会导致相关设备毁坏,因此产生的放射性对人体将会产生不同程度的伤 The 100 MeV cyclotron generates instantaneous radiation such as neutrons and photons due to the beam loss during commissioning and operation. The beam tubes, targets, and collimators will generate radionuclides under beam-bombardment. After the shutdown Decay of these radionuclides will have residual radiation. In the case of more serious loss of beam, it will lead to the destruction of related equipment, so the resulting radioactivity will produce different degrees of human injury
