Consumer products - Chemical hazard
What to do

Immediately stop using the recalled radon monitoring device.

Affected products

This recall involves Air Steward Portable Radon Monitor. The monitor is a black device with the text “Radon Monitor” below the LED screen. The LED screen displays “Coefficient of injury”.


This device may report a low value regardless of the actual radon level, with errors greater than 90%. This false reading misleads Canadians who are trying to assess whether or not their homes exceeds the national guidelines for radon. This may lead to continued exposure to radon and possible adverse health consequences.

Consumers should refer to the following website to learn about ways to detect radon with an approved test kit and ways to reduce radon in their home: Take Action on Radon.

As of August 23, 2022, the company has received no reports of radon related injuries in Canada.

What you should do

Consumers should immediately stop using the recalled radon monitoring device and dispose of it in accordance with the applicable transportation and waste requirements for electronic products. Consumers should measure radon in their home with other accurate device or seek professional service.

Consumers should only purchase radon test kits that are approved/certified by the Canadian National Radon Proficiency Program (C-NRPP), a Canadian radon certification program operated by the Canadian Association of Radon Scientists & Technologists (CARST) with oversight by Health Canada.
