Radon device
How LifeBasis RN-55 did in Health Canada's lab testing, its recall status and what its maker states, each with source and date.
Consumer electronic radon monitor
A consumer electronic radon monitor made by LifeBasis. Health Canada's lab tested it in a published study. This page is the record: the lab result, the recall status and what the maker says, each with its source and date. Health Canada's advice is to choose an electronic monitor "that has passed the C-NRPP performance testing." Its brochure is linked in the sources below.
Outside the 25% limit
In Health Canada's short chamber tests, this model's average error against the reference was over the 25% limit the study used.
