Who you’re working with
A certified professional, not a call centre.
Vancouver Island Radon Solution is led by Nasser Ferdosi, a C-NRPP–certified Radon Measurement Professional. When you book a test, you deal directly with the person who deploys the instruments, analyses the data, and explains what your numbers mean — no hand-offs, no guesswork.
The work is grounded in health physics and radiation protection: rigorous measurement against Health Canada’s 200 Bq/m³ guideline, methodology aligned with the Canadian National Radon Proficiency Program (C-NRPP), and membership in the Canadian Association of Radon Scientists & Technologists (CARST).
Beyond radon, the same measurement-first approach covers the full indoor-air-quality panel — mold, VOCs, asbestos, and particulate matter — for homes and small commercial buildings across Vancouver Island.

How we work
Three steps. One air-tight loop.
Every project follows the same arc — measure rigorously, fix practically, then prove the fix worked.
Step 01
Assess
Evaluate breathable air in residential and workplace environments.
Professional-grade equipment, Health Canada–aligned protocols, and a clear measurement plan tailored to your space.
Step 02
Advise
Explain what the results mean and the practical ways to improve your air.
Plain-language reports, source-by-source guidance, and concrete next steps — including referrals to certified professionals where needed.
Step 03
Verify
Re-test air quality after mitigation or remediation work is done.
Testing after the work shows whether levels came down. We close the loop with documentation you can keep.
By the numbers
