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 initial
activation.
Long-Term Mode: Requires continuous monitoring for at least 7
days to establish spatial average concentrations.
4
Q4： Where should the detector be positioned?
Answer:
Bedroom/Living room/family activity room/ Basement/Study/
Home Office/Children's room/game room
Location to avoid
Adjacent to cracks in the exterior wall or foundation: These points
may have abnormally high concentrations and do not represent the
entire room.
Kitchen and bathroom: frequent ventilation, large humidity changes,
and severe interference.
Closets and storage rooms: not frequently occupied, enclosed
space, not representing living areas.
Air conditioning vents, radiators, and in front of fans: airflow can
dilute or disturb radon gas.
On the floor or close to the ceiling: not suitable for breathing height.
Direct sunlight or humid areas: affecting the operation of the
instrument.
5
Q5： 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.
6
Q6： 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.
7
Q7： Why do radon readings exhibit sudden fluctuations?
Answer:
As a gaseous radioactive element, radon concentrations are
dynamically influenced by:
Atmospheric pressure changes Temperature/humidity variations
Ventilation rate shifts (e.g., door/window operation) Intermittent
soil gas infiltration
Maintain continuous monitoring for ≥48 hours
Conduct critical measurements only after maintaining closed
conditions for 12 hours
