What is a flaw detection operation?

Many situations in industry require flaw detection, which belongs to "special operations", mainly pressure vessels. People engaged in flaw detection and working around the flaw detection environment must have a full understanding of the hazards of flaw detection to ensure that they and others are not harmed. The flaw detection is called "nondestructive testing", and there are many detection methods. Among them, X-ray and γ-ray detection, if necessary safety protection is not done, long-term operation will cause serious harm to organisms and endanger life. Mainly manifested in the form of cancer and permanent infertility, such as breast cancer, liver cancer, brain cancer, bone cancer and so on. Detect cracks or defects in metal materials or parts. Commonly used flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetrant flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent penetrant inspection flaw detection and coloring flaw detection. Physical flaw detection is nondestructive flaw detection without chemical changes.

There will definitely be injuries, and you need to wear protective clothing and gloves when operating. It is best to stay as far away from the position that can be manipulated as possible. Industrial nondestructive testing will produce radiation, which may lead to infertility and even cancer.

Industrial radiation protection should do three things:

(1) distance protection, working away from radiation sources.

(2) time protection, don't work long hours.

(3) Shielding protection. The working area should have effective shielding devices.
