LoRAD Pro

The World’s Only LoRaWAN® Certified Radon Sensor

Professional real-time radon monitoring for building safety. Advanced IoT technology meets environmental protection.

Officially certified by the LoRa Alliance.

Why Radon Monitoring Matters

Radon is an invisible, odourless radioactive gas that poses serious health risks:

  • Cancer

    Second leading cause of lung cancer globally after smoking

  • Natural

    Naturally occurring from uranium decay in soil and rocks

  • Ubiquitous

    Affects offices, schools, homes, and industrial facilities worldwide

  • Avoidable

    Accumulates to dangerous levels in poorly ventilated buildings

The Most Accurate IoT-Based Radon Detection Solution

Professional LoRaWAN® Radon Monitoring for Real-Time Building Safety

LoRAD Pro delivers high-precision radon measurement through a professional-grade sensing system designed for continuous, real-time monitoring.

Engineered to exceed ANSI/AARST performance benchmarks, the device provides significantly enhanced sensitivity compared to minimum standards, enabling faster detection of elevated radon levels and more reliable long-term data.

Unlike traditional testing methods, which can take days or weeks to produce results, the LoRAD Pro provides near real-time insight supporting immediate visibility, ongoing trend analysis, and proactive risk management across buildings and property portfolios.

Frequently Asked Questions

  • Our Radon sensor features 30 counts per hour per pCi/L sensitivity, compared to the ANSI/AARST minimum standard of 2 CPH. This exceptional sensitivity enables detection of even minor radon fluctuations.


  • Yes! You’ll see your first reading in 10 minutes, with highly reliable data within 60 minutes. Full accuracy of <10% is achieved after 10 hours of continuous monitoring.

  • The premium aluminium alloy body provides durability, excellent heat dissipation, and a professional appearance suitable for any commercial environment.

  • It is not advised to move the sensor frequently as it is a sensitive scientific monitoring instrument that requires stable placement for accurate readings. Additionally, due to the cyclical nature of radon (which varies by season, weather, and building usage patterns), it is highly recommended that a sensor remain in situ for at least 12 months to effectively measure a building’s complete radon profile and identify all fluctuation patterns.

  • Typically 200-500 m² depending on room layout and ventilation. Our experts can help design optimal sensor placement for your building, however for most accurate results we recommend placing one sensor for every 50 m².

  • You can use an existing LoRaWAN network if available, or we can help you deploy a private network. A single, low cost gateway can cover an entire building or campus.

  • You can easily monitor all your sensor readings through our intuitive Web app at https://radonapp.nesosgroup.com/dashboard. The dashboard provides real-time radon levels, historical trends, multi-sensor overview, and customizable alerts – all accessible from any device with an internet connection.

  • Yes! We offer seamless integration with your existing infrastructure via native support for AWS SNS, Azure Service Bus (Microsoft Fabric), and Google Cloud Pub/Sub. For custom applications and IoT platforms, we also provide MQTT connectivity, enabling you to stream real-time radon data directly into your building management, analytics, or monitoring systems.
