Radon

Radon measures the concentration of radioactive gas in the air, formed naturally in the ground

beneath buildings, and shows if occupants face a hidden long-term health risk.

What is radon?

Radon is the measurement of the amount of naturally occurring radioactive gas present in the air, typically expressed in becquerels per cubic meter (Bq/m³) or picocuries per liter (pCi/L). Radon forms when uranium in soil and rock breaks down, and it enters buildings through cracks and openings in the foundation. It is invisible, odorless and found everywhere, and levels can vary greatly between buildings, and even between rooms in the same building. Measuring radon helps building, workplace and facility teams identify areas with elevated exposure and confirm that ventilation and mitigation are working.

● THE WHY 

Why does radon matter?

Radon isn't just a building metric. It is a serious health risk that is impossible to detect without monitoring, and one that employers and building owners are often responsible for managing.

Humidity 1 (1)

Protect occupant health


Radon is the leading cause of lung cancer among non-smokers. When inhaled over time, its radioactive particles can damage cells in the lungs. Children are especially sensitive, making radon monitoring essential in schools and daycare centers.
Radon 2

Meet regulations


Many countries set reference levels for radon in workplaces and schools, and building owners are often required to measure and take action. Continuous monitoring gives you the data and documentation needed to demonstrate compliance and fulfill your duty of care.

Catch changing levels early


Radon levels fluctuate with weather, seasons, ventilation and building use, and can rise sharply at night or when HVAC systems are switched off. Continuous monitoring reveals these patterns, helping you adjust ventilation and confirm that mitigation measures are working over time.
