My inspector, who said he was OCRMI certified ran a test during the home inspection but instead of giving me a color report he told me the levels. They were over 200 by a largish margin. What do I need to do.
Assuming the inspector was OCRMI certified (you can check here https://onradon.ca/find-an-ocrmi-professional/) then this was the right approach.
The Green/Amber/Red (GAR) OCRMI report is for the short-term radon test which lasts for 48 hours. Anything shorter than this is an indicative test only.
Anything over 200 Bq/M3 is an indication that radon is entering the property. If the measurement was over 250Bq/M3 you might want to consider opting for the ‘Red’ course of action.
