FAQ

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.

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.

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.

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.

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.

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

Q7： When should manual calibration be performed?

Answer: Initiate calibration under these conditions: Following significant environmental condition changes Upon detection of abnormal measurement deviations
