Portable Radon Meter for Measuring Soil Radon, Air Radon, Water Radon Concentration

Description :

　　Radon gas is one of the radiation sources that pose a threat to people's health. Before the construction of civil buildings, it is necessary to measure the soil radon concentration at the site. The impact of soil radon on engineering is not significant, and soil radon concentration measurement is not necessary for the project. When it is known that the average measured radon concentration in the local soil is high (greater than 10000 Bq/m3) or there are specialized geological fault structures at the project site, the project still needs to conduct soil radon concentration determination. When the soil radon concentration is not greater than 20000 Bq/m3 or the soil surface radon release rate is not greater than 0.05 Bq/m2 · s, radon prevention engineering measures may not be taken in the engineering design.

　　The Qingdao Lubo manufacturer recommends a device for detecting soil radon concentration that meets the new standards

　　GB 50325-2020 "Standard for Indoor Environmental Pollution Control of Civil Building Engineering"

　　GB/T 14582-93 "Standard Measurement Method for Radon in Environmental Air"

　　T/CECS 569-2019 "Standard for Radon Detection in Indoor Air of Buildings"
