2.Application
● Used for environmental radon monitoring in mines, basements and
poorly ventilated residential buildings.
● Investigation and evaluation of radon concentration in soil at construction
site.
● It can be used for mineral resource exploration, engineering geological
exploration, environmental radon concentration monitoring in related
departments of nuclear industry, and radiation detection of radon
concentration in geological investigation.
3.Limits on radon concentration
The concentration limit for radon in the civil built environment varies from
country to country (our equipment defaults to 148Bq/m³), but the following
basic standards are generally used.
EPA (United States standards )
WHO standards
EURATOM
(European standards)
The simplest way to reduce indoor radon concentration is to
strengthen indoor ventilation. When the radon concentration exceeds
4pCi/L(148 Bq/m³), ventilate for at least 10 minutes or more.
Note: 1 pCi/L = 37 Bq/m³.
4.Features
● Self-developed high precision radon pulse ionization chamber sensor.
● 3.4 inch 480*480 high-resolution capacitance touch color display.
● Built-in temperature and humidity sensor to detect the changes in the
ionization chamber timely.
≤4pCi/L （Or≤148Bq/m³）
≤100Bq/m³（when ＞300 Bq/m³, it is strongly
recommended to take corrective measures）
≤300Bq/m³
