Plinio Neto, partner and certified radon professional

Plinio Neto is a partner in the company and the person who comes to your home. He places and collects the detectors, assesses foundations, designs and installs the mitigation systems and runs the follow-up tests. He also reviews the technical content of this site before it is published.

Health Canada recommends hiring a professional certified by C-NRPP for radon worksource.

Why "measured, not guessed"?

Because nothing about radon can be judged by eye. A home's age, its neighbourhood and the result next door do not tell you its level. Health Canada recommends testing every home, wherever it is and whatever kind of building it issource. So every recommendation we make starts from a measurement, and every system we install ends with one: a follow-up test that shows what changed.

It also means saying what we do not know. We will not tell you that an area is fine or that a system will reach a particular number, and when a test shows that no action is needed we say that too.

Which standards do we follow?

• Health Canada's guideline of 200 Bq/m³ as an annual averagesource, as the reference for every result.
• Health Canada's measurement guide, which calls for tests of three to twelve months and never less than 91 dayssource.
• CAN/CGSB-149.12-2024, the national standard for radon mitigation in existing buildingssource.
• C-NRPP's requirements for certified measurement and mitigation professionals.

How do we check what we publish?

Every health statement, number, regulation and standard on this site is tied to a source: Health Canada, the World Health Organization, the Canadian standards body, or published research. Each page lists its sources at the bottom. Before a fact is used it is opened at the original source and the wording is compared; facts that have not been through that check do not appear on the public site.

• We paraphrase and link; we do not copy long passages.
• Where studies give different figures, we show each with its year.
• Prices are our installer's own, not averages gathered from other companies.
• The "Updated" date on a page changes only when its content changes.
• If you find an error, email contact@calgaryradonpro.ca and we will correct it.

What do we do with test results?

Your result is yours. With your permission we may include it in area-level statistics with everything that could identify a household removed. We never publish names or addresses. The details are in our privacy policy.
