Radon detector DM120A
Radon detector
This radon detector is an efficient, portable device capable of monitoring radon concentrations in real time. Radon is a colorless, odorless, radioactive gas that can cause lung cancer and respiratory problems when exposed to high concentrations over a long period of time. Therefore, it is critical to use this instrument for radon monitoring in environments such as homes, building construction, schools, and public spaces. The device is easy to operate, just turn it on, place it in the detection area, and obtain radon concentration data in real time. Radon can enter buildings through crevices in floors, walls, and pipes, and detecting and controlling radon levels is important to ensure a safe living environment. With their ease of use and efficiency, our radon detectors are ideal for keeping your home and work environment safe.

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:
Floor-level measurement: Place the device horizontally on the floor.
Wall-proximate measurement: Mount the device vertically on the wall.
Breathing-zone measurement: Position the device approximately 1 meter above floor level.
Note: Avoid areas with airflow disturbances such as air conditioner vents or radiators.
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
Resolution:
Maintain continuous monitoring for ≥48 hours
Conduct critical measurements only after maintaining closed conditions for 12 hours
8
Q8: When should manual calibration be performed?
Answer:
Initiate calibration under these conditions:
Following significant environmental condition changes
Upon detection of abnormal measurement deviations
