Our 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.
Langdeli Technology Co., Ltd. is a professional manufacturer with 10 years of experience in producing testing instruments, committed to providing customers with high-quality and high-performance testing instruments. The company has advanced production equipment, a professional R&D team and sales team, as well as its own factory, production workshop, and office buildings.
detectors, noise detectors, temperature and humidity detectors, combustible gas detectors, radiation monitors, alcohol measuring instruments, etc.
Our Production line:
We are well aware that product quality is the lifeline of a company, so we always adhere to high-quality and high standard production processes. We have a professional quality inspection team that strictly controls every step from raw material procurement to production processes. We focus on the quality and performance of our products, continuously optimizing production processes and quality management to ensure that every product meets national standards and certification standards.
Our Facilities Includes (not all):
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 initial activation.
Long-Term Mode: Requires continuous monitoring for at least 7 days to establish spatial average concentrations.
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.
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.
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.
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
Q8: When should manual calibration be performed?
Answer:
Initiate calibration under these conditions:
Following significant environmental condition changes
Upon detection of abnormal measurement deviations
