Is the thickness gauge harmful to the human body?
Is there any radiation when using a thickness gauge? How harmful is it to the human body? How long is the appropriate use time? This is a question that still has no clear answer in the industry. Some people say whether thickness gauges are harmful to the human body? This depends on the type of thickness gauge.
If it is an ultrasonic thickness gauge, in principle, ultrasonic waves have no radiation, they are a vibrating mechanical wave. However, when people are affected by ultrasound for a long time, it will cause slight heating of human tissues; when the frequency is higher, the heating will become more severe, causing the water molecules in the human body to be burned and the surrounding tissues to be destroyed. This is dangerous for a long time. Therefore, it is harmful for high-power and high-intensity ultrasonic waves to continue to act on the human body.
If it is a radioactive source thickness gauge, 0.5 meters is very dangerous. And it is worth mentioning that the degree of radiation exposure is not only related to distance and exposure time, but also to the sealing condition of the radioactive source. If the sealing is not good, the degree of radiation exposure will be more serious.
Therefore, when using the thickness gauge, appropriate protective measures must be taken to prevent electromagnetic radiation pollution.
First of all, in terms of labor and production safety, magnetic particle inspection workers should be equipped with anti-electromagnetic radiation clothing (containing metal components that can block electromagnetic radiation to a certain extent), electromagnetic radiation protective glasses, etc. to effectively prevent electromagnetic radiation. It is recommended to wear a radiation dosimeter, which is mandatory for radiation workers to be worn by the environmental protection department. It is a protective measure to regularly monitor the radiation dose of workers.
Secondly, attention should be paid to strengthening physical exercise and enhancing one's own resistance. Radiation of the same energy has different effects on different people. People with strong resistance have a much greater ability to self-recover than people with weak resistance. Eat more foods rich in vitamin A, C and protein such as carrots, bean sprouts, tomatoes, rape, kelp, cabbage, lean meat, animal liver, etc. to enhance the body's ability to resist electromagnetic radiation.
