OCRMI Short-term radon measurement
Traffic light results
In order to simplify the recommendations regarding the radon levels found in a home, the results of the OCRMI short-term measurements will be given as a traffic light response.
The property tested will be given on of either a GREEN, AMBER or RED result. The actual level of radon will not be provided, although it will be recorded by the inspector. The reasoning is that it is important a decision is made regarding the result. By not returning the actual levels, any decision to argue over a minimal difference in levels is avoided.
If the property radon measurement results in a GREEN report, it is determined that the radon levels in the property are at a level where mitigation may not be able to lower them any further. They are considered, at the time of the measurement, to be at the ALARA level (As Low As Reasonably Achievable). This does not mean the radon is not entering the property. Nor does it mean that radon levels, measured over a longer or different period in time, will not be found to be higher. No immediate action is considered noteworthy. It is still recommended that regular testing is carried out to ensure levels do not change. If any modifications to the property are performed, a measurement should be taken immediately after changes are made. Health-Canada recommends long-term testing (3-months or longer) every 2-3 years.
If the property radon measurement results in an AMBER report, it is determined that the radon levels in the property are at a high enough level where a long-term test should be carried out to establish the health risk to any residents. Obviously, in a Real-Estate transaction, this presents a problem. In order to perform a long-term measurement, the sale would have to be held up until the measurement is completed. This is impractical. The recommendation is that money is set aside in escrow to cover the costs of the long-term test and any possible remediation. If remediation provides unnecessary, the money is released to the sellers. If however, mitigation is found to be required, the escrow funds will be used to complete the mitigation. Alternatively, the buyer and seller could come to an arrangement for a monetary adjustment to instigate mitigation immediately. These funds should be entered into an escrow account for the buyer and paid out to any mitigation provider to ensure the work is done professionally by a C-NRPP certified remediator.
If the property radon measurement results in a RED report, it is determined that the radon levels in the property are so high that a long-term test would be a waste of time and mitigation should be carried out as soon as possible. The recommendation is that money from the purchase is set aside in escrow to cover the costs remediation. Once again, the funds should be entered into an escrow account to ensure the work is done professionally by a C-NRPP certified remediator.
