Is the coating thickness gauge harmful to the human body?
Is there any radiation when using a thickness gauge? How much harm does it cause to the human body? What is the appropriate usage time? This is a question that still has no clear answer within the industry. Some people say, is a thickness gauge harmful to the human body? This depends on the type of thickness gauge.
If it is an ultrasonic thickness gauge, in principle, ultrasonic waves do not radiate, they are a type of vibration mechanical wave. However, long-term exposure to ultrasound can cause mild fever in human tissues; When the frequency is higher, the heat will become more severe, causing water molecules in the human body to be burned and surrounding tissues to be damaged, which can be dangerous for a long time. Therefore, high-power and high-intensity ultrasound continuously acting on the human body is harmful.
If it is a radioactive source thickness gauge, 0.5 meters is very dangerous. Moreover, 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 radiation source. If the sealing is not comfortable, the radiation level will be more severe.
Therefore, when using a thickness gauge, appropriate protective measures should be taken to prevent electromagnetic radiation pollution.
Firstly, in terms of labor production safety, magnetic particle inspection personnel should be equipped with anti electromagnetic radiation clothing (containing metal components that can have a certain blocking effect on electromagnetic radiation), electromagnetic radiation protective goggles, etc. to effectively prevent electromagnetic radiation. It is recommended to wear a radiation dose meter, which is a mandatory requirement for radiation workers by the environmental protection department. Regular monitoring of the radiation dose received by workers is a protective measure.
Secondly, attention should be paid to strengthening physical exercise and enhancing one's own resistance. The impact of radiation of the same energy on different people is different, and people with strong resistance have much greater self recovery ability than those with weak resistance. Eat more foods rich in vitamins A, C, and protein, such as carrots, bean sprouts, tomatoes, rapeseed, kelp, cabbage, lean meat, and animal liver, to enhance the body's ability to resist electromagnetic radiation.
