Letter - Promotion & Awareness
Don’t use “safe” or “low risk” The lower the Bq/m³ the better Lowest reasonably possible Health Canada suggested mitigation
timelineso 200 – 600 Bq/m³ fix within 2 yearso >600 Bq/m³ fix within 1 year
Transparency of results (notify clients) Influencing factors (seasons, HVAC,
renovations, pressure differences)
