The SPT57 regional radiation monitoring system adopts a split type instrument consisting of a radiation dose online controller SPT57 (hereinafter referred to as the controller) and a radiation dose online monitor RP32GM (hereinafter referred to as the detector). The detector detects radiation dose data and transmits it to the controller through wireless or wired transmission, displaying the detected data and its status. This system is suitable for radiation protection safety monitoring in X-ray and gamma ray sites. The instrument can be selected as a high-sensitivity detector or a high range detector according to the monitoring needs of the usage site. It is an ideal instrument for X-ray and gamma radiation monitoring in radiation source application sites such as industrial radiation source application sites, environmental laboratories, irradiation rooms, nuclear medicine, nuclear material storage and transportation, and security checks.

● Functions and features
