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):
PrecautionsTo ensure accurate data reliability and prolong device service life,
strictly adhere to the following operational protocols:
I. Pre-Detection Preparation
1. Environmental Sealing
Close all windows, doors, ventilation systems, and air conditioning for at least 12 hours prior to detection to stabilize indoor
air conditions.Seal potential radon entry points (e.g., floor drains, sewer openings).
2. Device Placement
Location: Prioritize placement in frequently occupied areas (e.g., bedrooms, living rooms). Avoid high-humidity or
airflow-disturbed zones (e.g., kitchens, bathrooms).
Stability: Place the detector on a flat, stable surface to avoid vibrations or tilting.
II. Operational Protocols During Detection
1. Environmental Control Prohibit opening windows, doors, fans, or air purifiers during detection.
Avoid smoking, combustion activities, or aerosol sprays in the detection area.
2. Device Management
Long-term detection (≥3 months): Ensure uninterrupted power supply. Relocating or interrupting the device during operation is
strictly prohibited.
Short-term detection: Strictly adhere to the preset duration (e.g., 48 hours). Early termination is not permitted. Seal potential
radon entry points (e.g., floor drains, sewer openings).
III. Device Maintenance and Interference Mitigation
1. Protective Measures
Avoid contact with water, oil, dust, or direct sunlight. Clean only with a dry cloth. Keep the device away from strong
electromagnetic fields (e.g., microwaves, transformers) and extreme environments (>40°C or <10°C).
2. Calibration Requirements
Manual calibration: When the environment changes greatly or the reading is abnormal, please calibrate manually.
Post-impact recalibration: Immediate recalibration is mandatory after severe shocks or drops. Storage: Remove batteries and store
in a dry, cool environment if unused for extended periods.
IV. Data Interpretation and Response
1. Data Validity
Short-term results are for reference only; long-term data
(≥3 months) more accurately reflect.
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.
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.
Answer:
Initiate calibration under these conditions: Following significant environmental condition changes
Upon detection of abnormal measurement deviations
