Information on Radon Gas Testing
How is Radon Gas Measured ?
- Radon gas is typically measured with a "radioactivity" (alpha particle) detector appropriately placed in your house or building.
- The best time to detect radon gas is in the fall-winter-early spring months when houses are closed up more and radon levels are highest, although a radon gas test can be performed anytime.
- Normal "short-term" (ST) detection
- time lines are usually from 2 to 90 days (using traditional charcoal, charcoal liquid scintillation, alpha trak or E-perm detectors, with laboratory analysis)
- I use a "short-term integrated reading" (2-7 days) with Continuous Radon Monitor (RadStar RS 300i) for or Rad Elec E-Perm system for
- immediate radon gas levels
- real estate transactions (co-located detectors)
- Tarion New Home Warranty preliminary test
- school or public buildings followup testing
- post-mitigation level confirmation
- the Radon Away Rad Star RS300I gives integrated hourly readings over the 2-7 day test period.
- Short-term (ST) readings fluctuate widely and are only indicative of levels at a particular point in time and should not be used for predicting annual levels or for mitigation decisions.
- requires "closed house" conditions for 12 hours preceding and during test periods
- client receives a data printout and graph (RS300i) immediately after the testing; no waiting weeks for your results
- I also use a "short-term integrated reading" (10-30 days)
- I principally use the Rad-elec E-Perm system for these measurements
- I can also use the Landauer Rapidos Alpha Track detector for 10-30 day measurements, however the report takes at least 3-4 weeks to generate due to detector analysis in the USA.
- "long-term" (LT) reading (91-365 days) is the most commonly used test
- recommended by Health Canada, Middlesex-London Public Health Department, et al
- this provides:
- better accuracy; daily and seasonal fluctuations are minimized
- better reflects annual radon gas levels
- for mitigation (remedial action) determination, for Tarion confirmatory tests
- requires normal house living conditions during the test
- I use the Rad-Elect E-perm system or alpha track detector (Landauer Radtrak2) for long term measurements. Any short-term reading above the Health Canada limit (200 Bq/m3), should be followed up by a longer term test. Mitigation decisions MUST be based upon long-term test results. Radon levels fluctuate daily and the long term testing procedures are designed to average the results over the test period.

Why select me?
As an educator at both the college and secondary school levels, I have been involved in various aspects of health and safety training and education for over 35 years. My formal education involves :
- Hon. B.Sc Microbiology (UWO)
- M.Sc. Phytopathology (UWO)
- B.Ed. Education ( Brock University),
- College Certificate - Occupational Health and Safety (Fanshawe College)
- numerous health and safety certifications
- Radon gas measurement and analysis certification (C-NRPP) (Canadian - National Radon Proficiency Program); C-NRPP has strict protocols and guidelines which must be followed for accurate measurements. In order to maintain my certification, the following must be done each year:
- CE (Continuing Education) to enhance my knowledge and training,
- a strict Quality Assurance (QAP) Program must be submitted and followed
- instruments must be calibrated and cross -checked, and
- undergo device performance testing in Ohio or Colorado Springs to prove that I am competent in measuring, interpreting and analyzing the data.
- C-NRPP No. CRT 201319
I have a true passion for health and safety and sincerely believe in the importance of radon gas detection at an affordable price.
I AM NOT INVOLVED IN RADON MITIGATION so I do not have a vested or financial interest in removing the radon or convincing you that you need a radon mitigation system - only in detecting it. There is a C-NRPP-Certified mitigation contractor in SW Ontario that I recommend that will facilitate mitigation and will give you a free estimate if needed.
