Long-term operation and maintenance of c-arm and dr medical equipment x-rays are harmful

While I don't understand the maintenance of those professional equipment, but if there is radioactive material, because it will release rays of decay, long time will induce cell mutation into cancer cells, human T-cell immunity can be clear of these diseased cells, but time will inevitably evolve, cancer cells belong to the malignant proliferation of cells, which may lead to cancer. You should have protective equipment when it comes to this kind of equipment when you repair, but I personally think that there is still a risk for a long time. Domestic production of this type of equipment is less, many are imported back from abroad, maintenance of this type of equipment should be very popular, so do not do have to consider their own ~ personal opinion, I hope to help you.
