Radiation Detection and Analysis

Radiation is the phenomenon that part of the electromagnetic energy emitted by the field source spreads away from the field source and then no longer returns to the field source, which will cause great harm to human body. With excellent radiation detection professionals and advanced detection instruments, CTI can accurately detect the radiation intensity and analyze whether it meets the national standard, so as to avoid unnecessary injury to human body

◉ Service Background

Radiation, as a possible hazard in modern life, can cause great harm to human body, ranging from insomnia, dizziness and headache to fetal malformation and cancer. Although there are a variety of radiation protection methods and tools, radiation can not be seen and touched after all, and people can not find its existence without instruments.

As a listed third-party testing institution, CTI has advanced radiation testing equipment, professional technical support and testing team, which has been recognized by the national CMA team. Careful working attitude and professional detection technology can help you find the presence of radiation hazards around you as soon as possible and analyze whether it meets the national limited standards. It allows you to identify the source of radiation early and make appropriate actions to avoid unnecessary hazards.

◉ Requently asked Question

Q: What are the major radiation hazards at present?

A: At present, there are signal transmitting base stations, high-voltage lines, some medical equipment and nuclear energy, etc.

Q: What is the more effective way to prevent radiation at present?

A: The most effective way is to find the source of radiation and isolate it. If the source of radiation cannot be completely isolated, you can wear radiation protection clothing, radiation glasses and radiation protection blanket.
