RECM-03 is a portable surface radon release rate measuring instrument with typical advantages in design and structure. It can "real-time" and "quickly" measure the radon release level on the surface of the medium. It can be used for measuring the radon release rate on underground engineering, underground mines, tourist caves, nuclear facilities, tailings ponds, building materials, soil, ground and other surfaces. It is an essential device for searching for radon sources and radon control. Suitable for the determination of soil surface radon release rate required by GB50325 "Code for Indoor Environmental Pollution Control of Civil Building Engineering" (2006 edition), it can also be used for radioactive detection and identification of building materials such as stone, cement, coatings, etc. before construction or decoration, to guide the selection of high-quality building materials.

Technical Indicators:
