Frequently asked questions
When should I start?
The heating season is the preferred time.
Where do I place it?
In a regularly used room, on the lowest lived-in level, 0.8 to 2 m above the floor.
Can I place it myself?
Yes. Open the envelope and watch the short video: activation takes one simple motion.
When do the results arrive?
The 91 days are the time in the house. The detector reaches the laboratory within 48 hours, then the report is sent within 2 business days after that receipt. Weekends and holidays do not count in those 2 days. Shipping is in addition to the 91 days.
How do I send it back?
Three steps: the portal (order number and checkout email), two clicks for the date, then the envelope in the mailbox or on the porch. The same day; after 4 p.m., the next day.
What if the result is high?
Health Canada recommends corrective action above 200 Bq/m³. A C-NRPP certified professional explains the options.
Can I order more than one detector?
Yes. Each one is analysed.
What about a shorter measurement?
A 4-day short-term measurement gives a first assessment. The 91-day test remains the reference for annual exposure.
