Ms Laura Burke:

There has been research, along with research into the reasons for a lack of uptake. There has been assessment with regard to the radon control strategy on what has worked and what has not worked. Some of the scientific information evolves as time moves on. Yes, we have carried out reviews of both the radon control strategy and where we are at with it. We must also remember that it is a percentage of the population, as Dr. Ryan has identified. As the population goes up, that can have an impact as well.
