The SPT1200 wound radioactive detector uses a sensitive semiconductor detector and a probe cover, which can be used for detecting low-level alpha radiation contamination on the surface of human wounds. It can also measure the external gamma dose rate level of human wounds after being contaminated with nuclides. It has good detection efficiency, high reliability, and convenient operational characteristics. This instrument is controlled by a microcontroller and can continuously record and store measurement data, as well as export data to a USB flash drive.

This device can be used in various fields such as nuclear emergency (as a supporting product for military nuclear emergency boxes), nuclear medicine, nuclear power plants, nuclear fuel production, transportation, storage, and inspection. The instrument control function includes: background measurement timing selection, pollution measurement timing selection, alarm threshold setting, sound and light alarm, etc.
