Why Monitor Radon Gas?

Radon is a naturally occurring radioactive gas that is colorless, odorless, and tasteless, requiring specialized instruments for detection. Originating from soil, it can infiltrate buildings through cracks and openings in foundations, accumulating in indoor spaces. The World Health Organization (WHO) identifies radon as the second leading cause of lung cancer worldwide, after smoking. Due to its temporal variability, continuous monitoring is essential for reliable risk assessment.

Key Features of the Aranet Radon Plus PRO

This advanced device provides continuous radon monitoring with high accuracy and reliability. Equipped with sensitive sensors, wireless communication on the ISM Sub-GHz band (Aranet), and a low-power E-Ink display, it allows real-time radon level readings. Long battery life and robust construction make it ideal for permanent indoor air quality monitoring in institutional and commercial buildings.

Technical Specifications of the Radon Detector

Sensor Performance – Radon Concentration

Important Technical Notes

• Accuracy is ensured after at least 1 hour of continuous operation.
• The device is sensitive to static electricity, which may temporarily affect radon readings.
• Calibrated for measurements up to 4000 Bq/m³; readings up to 7900 Bq/m³ possible with reduced accuracy.
• Accumulation of long-lived radon progeny inside the chamber can cause gradual reading increases over time.

Compliance and Regulations

Decree-Law No. 108/2018 mandates radon exposure assessment in buildings across mainland Portugal, with a reference level of 300 Bq/m³ to protect public health. Continuous monitoring is the only reliable method to verify compliance with national limits.

Frequently Asked Questions (FAQ)

1. What is radon, and why should I monitor it?

Radon is a natural radioactive gas, colorless and odorless, that can accumulate indoors and pose serious respiratory health risks.

2. Where should I install the Radon Plus PRO?

Place it in frequently occupied rooms, about 1 meter from the floor, away from windows or direct ventilation systems.

3. Is device calibration necessary?

The device is factory-calibrated. Periodic recalibration depends on institutional policies, but the sensor exhibits minimal drift.

4. How can I view the data?

Measurements are wirelessly transmitted to the Aranet PRO base station and can be accessed in real-time via web or app.

5. What happens when the battery runs out?

The battery lasts several years and can be replaced by an authorized technician when needed.
