BG9531 can be used for measuring the dose equivalent (rate) of X-ray and gamma ray radiation protection, as well as for measuring the dose equivalent rate of pulse exposure radiation. It can be used for environmental protection, health, customs, and source related enterprises. Its pulse exposure dose rate measurement function is particularly suitable for measuring leakage dose rates in hospital radiology departments, accelerator treatment rooms, and other places involving pulse X and gamma radiation. BG9531 has a Bluetooth communication interface, which can directly communicate with mobile phones. Combined with a radiation monitoring app, it facilitates users to query and manage measurement data.
