What harm does industrial flaw detection do to human body? My friend asked me to have a flaw detection. Who can elaborate? Thank you.

Any work is dangerous, as long as it is completed safely, there is no problem. I have been doing flaw detection for 30 years, and I have never heard of casualties caused by dry flaw detection.

The main hazard of flaw detection is the radiation used in radiographic inspection, which is similar to that of doctors engaged in radiography in hospitals. X-rays are mainly used to prevent acute radiation injury. Short-term high-dose radiation will cause serious harm, while long-term low-dose radiation is inconclusive. As long as you pay attention to safety at work, there will be no problem.
