The requirement
Radon is a natural radioactive gas that seeps out of granite and some other rocks, and it is the second biggest cause of lung cancer after smoking. The Channel Islands, Cornwall, Devon, parts of Wales, Scotland and Northern England, and large parts of continental Europe all have areas where levels in buildings can be high.
In the UK, 300 Bq/m³ is the reference level for workplaces under the Ionising Radiations Regulations 2017, and 200 Bq/m³ is the Action Level for homes. The usual way to check is a passive detector left in place for three months and then posted to a laboratory. That gives one average figure, months after the event, and nothing in between.
Our approach
Continuous LoRaWAN radon monitors measure every hour and send their readings over the network. That gives you:
- a live reading for every monitored room, and alerts when levels pass a threshold you set;
- daily and seasonal patterns, which show whether ventilation or a sump is actually working;
- evidence before and after remediation, without waiting another three months.
We have developed our own plug-in, mains-powered LoRaWAN radon monitor with a manufacturing partner, designed for CE, UKCA, ISO 11665 and LoRa Alliance certification, and it is available to order now. We have also written the integration guide and decoders for ChirpStack, The Things Network and Helium. Because it is mains powered it can report frequently for years with no battery changes.
