RTM-IRadon and thorium measuring instrument

Radon and thorium measuring instrumentFor "real-time" and "fast" testingRadon or thorium gas（²²²Rn/²²⁰Rn concentration, radon or thorium daughter concentrationThe multifunctional instrument can be used for investigating pollution sources in underground engineering, underground mines, tourist caves, nuclear facilities, uranium and thorium mines, and associated radioactive mines. It is an essential device for analyzing and controlling pollution sources in the development, smelting, and processing of accompanying mineral resources, and meets the application requirements of GB/T14582-1993 and the International Commission on Radiological Effects for radon and thorium daughter monitoring and dose estimation.
