With the widespread application of radiation equipment in the fields of nuclear power, X-ray equipment, and medical radiology, the requirements for radiation protection are increasingly valued. Wanyi Technology is committed to radiation detection and prevention, and has launched the GM-100 series of personal dosimeters for personal safety protection. It uses an all metal GM counter imported from Russia, which has the characteristics of long service life, stable data, and good consistency, It has also been used by many European and American companies to develop personal dosimeters and other radiation detection instruments.
The GM-100 series personal dosimeters of Wanyi Technology brand can quickly and in real-time detect the hardness of the environment or products β，γ And X-ray, and quickly search for radioactive sources. The alarm threshold and dose mode that can be set by the instrument are more suitable for various radiation protection fields such as medical protection, nuclear power plants, X-ray machines, radiation leaks, etc.
