BTI currently offers two types of passive, cost-effective radon monitoring kits – the charcoal canister (short-term test) and the AT-100 (Alpha damage track long term monitor). The charcoal canister is exposed for a period of two (2) days, while the AT-100 can be exposed for a minimum period of 91 days up to a maximum of a year. Both detectors must be sent back to BTI for analysis using EPA protocols and procedures.
The charcoal canister is ideal to get a fast estimate of the amount of radon in your home. Results are back to you within a week of sending the canister back to BTI. If the results are greater than 200 Bq/m3, it is recommended that a repeat measurement using another canister is performed.
The AT-100 is a longer term measurement device that offers the advantage of averaging seasonal variations in radon concentrations (e.g., winter versus summer when windows are closed reducing potential house ventilation). The disadvantage of the AT-100 is the longer measurement period and the longer analysis period – results are back to you within a month of sending the AT-100 back to BTI.
|The Canadian Radon Guideline, established by Health Canada in conjunction with the provinces and territories recommends:
The “normal occupancy area” refers to any part of the dwelling where a person is likely to spend several hours (greater than four) per day. This would include a finished basement with a family room, guest room, office or workshop. It would also include a basement apartment. It would exclude an unfinished basement, a crawl space, or any area that is normally closed off and accessed infrequently (e.g. a storage area, cold room, furnace room, or laundry room). The aim of the Canadian Radon Guideline is to remediate and reduce the radon concentration to less than 200 Bq/m3. If the radon concentration is found to be greater than 600 Bq/m3, the remedial actions are recommended to be completed in less than a year; between 200 Bq/m3 and 600 Bq/m3, the remedial actions should be completed in less than two years. This Government of Canada guideline is based on the guidance approved by the Federal Provincial Territorial Radiation Protection Committee (FPTRPC). The guideline is based upon current scientific understanding and will be reviewed and updated as appropriate.
