C-NRPP-Certified Radon Gas Testing - Your Family's Health is Key

C-NRPP-Certified Radon Gas Measurement

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
  •  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 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 immediately after the testing; no waiting weeks for            your results
  •  I also use a "short-term integrated reading" (10-30 days)  with Continuous Radon     Monitor (Corentium Pro)  for those who want a longer test than 7 days. A report giving average     radon levels, humidity, temperature and barometric pressure readings is emailed to the client         upon completion of the test. I can also use the Landauer Rapidos Alpha Track detector for 10-         30 day measurements, however the report takes at least 10 days to generate due to detector       measurement and analysis in the USA. 
  •  "long-term" (LT) reading (91-365 days)
  • 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 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.
