Mr. Michael Layde:

Agreed. That is very much what we are attempting to do. The new regime will require a system of mandatory certification by approved certifiers, with legal responsibility on the part of such individuals.

Contrary to common perception, that is not the position under the current legal framework where professional opinions are offered. This will be a mandatory system of certification with the person ultimately having legal accountability and it will be an appropriately qualified person. We believe it will be far more robust in that sense than the current arrangement. I will ask my colleague to reply on the radon issue.
