FAQ
1
Q1： What is radon gas?
Answer:
Radon gas is a radioactive noble gas primarily originating from the
decay of uranium in soil and rock formations. It typically infiltrates
buildings through ground penetration. With a higher density than
air, radon tends to accumulate in lower areas, particularly near
floor surfaces.
2
Q2： Does the radon concentration measured at floor level by the detector equal airborne radon concentration?
Answer:
No. Radon concentrations near floor surfaces may exceed those
at elevated positions due to radon's higher density, which causes
gravitational settling. Measurements taken directly on the floor
reflect source-proximal concentrations, whereas central or elevated areas of the room may exhibit lower values.
3
Q3： How long does the device require to display accurate
readings?
Answer:Measurement duration varies by operational mode:Rapid Mode: Delivers stabilized readings within 48 hours of
initialactivation.Long-Term Mode: Requires continuous monitoring for at least 7days to establish spatial average concentrations.
4
Q4： Can this device test radon in water?
Answer:
This instrument is exclusively designed for air medium analysis.
For aqueous radon testing, use dedicated hydro-radon testing
equipment to prevent sensor damage.
5
Q5： At what concentration threshold should corrective action
be taken?
Answer:
Per WHO safety guidelines:
2.70 pCi/L (100 Bq/m³): Implement mitigation measures (e.g.,
enhanced ventilation, crack sealing).
8.10 pCi/L (300 Bq/m³) : Engage certified professionals for
structural remediation.
6
Q6： Why do radon readings exhibit sudden fluctuations?
Answer:As a gaseous radioactive element,radon concentrations aredynamically influenced by: Atmospheric pressure changes
Temperature/humidity variationsVentilation rate shifts (e.g.,door/window operation) Intermittentsoil gas infiltration
Resolution:Maintain continuous monitoring for >48 hoursConduct critical
measurements only after maintaining closedconditions for 12 hours
7
Q7： When should manual calibration be performed?
Answer:
Initiate calibration under these conditions:
Following significant environmental condition changes
Upon detection of abnormal measurement deviations
