Continuous Radon Monitor
C-NRPP ID 201643CRT Radon Certified http://c-nrpp.ca/find-a-professional 

We can provide continuous Radon monitoring as follows:

  • Please inquire about fee for Continous Radon Monitor travel, setup and retrieval, within HRM
  • travel to the building selected
  • evaluate each building and recommend a testing approach designed to make sure you get reliable results
  • explain to the attendant at each building how proper conditions can be maintained during the radon test
  • return to the building to retrieve monitors after deployment
  • analyze and report measurement results
  • provide independent test results within 48 hours of all monitors retrieved

Sun Nuclear Corporation Professional Continuous Radon Monitor Model 1027

The Model 1027 Professional Continuous Radon Monitor is a patented electronic detecting device using a diffused-junction photodiode sensor to measure the concentration of radon gas. Ambient room air, laden with radon, diffuses into the monitor's detection chamber. Radon decay by-products emit alpha particles which are detected by the photodiode. A numerical display shows the average radon gas concentration. The interval storage stops after 90 one hour intervals; however, the "average" and "current" display values continue to update during the entire test, even if the test period exceeds the maximum storage of 90 intervals. The "average" display is the measured long-term average radon gas concentration in pCi/L. This is the cumulative average of the entire period since the memory was last cleared. This value is not lost if the monitor loses power. The "current" display is the measured short-term radon gas concentration. This is a rolling average of the most recent 12 hours.

At the end of the monitoring period, the results are available in any of three forms: numerical display on the control panel, or using the data ports, the operator can print a complete report or download the data to a personal computer. After obtaining the report data, the operator can clear the memory and immediately begin another test. The unit is completely reusable and operated from standard line power and includes a 9 volt battery which provides backup power. The printer need not be present during testing. The radon monitor can be moved from the test site and the report printed later.

Corentium Pro Radon Monitor

Corentium Pro samples indoor air through a passive diffusion chamber, using alpha spectrometry to precisely calculate the radon level. Radon is detected using silicon photodiodes to both count and measure the energy of alpha particles resulting from the decay chain of radon gas. Stores up to 5 years of data at 1-hour intervals.
