scientists , we would be seeking out new and innovative ways of solving a problem . However , simplified models or inaccurate statements inhibit growth and innovation . It has been my experience when students contacted me about a very difficult mitigation , that many of them forget what the real objective is , which is to reduce radon related lung cancer to as low as reasonably achievable . Yes , Active Soil Depressurization is a great tool , but it doesn ’ t have to be the only tool , especially when the tools may already exist within a building for reducing radon decay products, but they are unaware of it because they are either unaware of their significance or do not know how to measure radon decay products .
In closing , I am reminded of several conversations with Dr . William Field regarding the research indicating that 2 / 3 of the radon induced lung cancers come from exposuress less than
4.0 pCi / L and the only way to reduce exposures further is via radon decay product reductions.
For those who would like to learn more about radon decay measurement and reduction as another tool in quantifying and reducing radon risks , we encourage you to take the following course , approved by both NRPP and NRSB :
