[QUOTE] [QUOTE="Phil"] [1] Who I never met - he died of cancer in 1977. The side effect of being a stonemason in Cornwall - all that working with granite led to much higher rates of various cancers from the radon exposure.[/QUOTE][/QUOTE] [QUOTE] When we doing the great radon survey in ???? my boss stated the *opinion* that he would not live in parts of Cornwall rent free.[/QUOTE] 1986? I was working in North Devon then and was The Man for that bloody Job too. We had to work quite hard to get people to accept detectors in some cases, frequently ending up twisting the arm of Parish Clerks or councillors, just to be able to site a detector in the right spot. A lot of residents, especially the real locals, werwe quite worried about it, but just didn't want to know. I well remember meeting a colleague from Mid Devon who had Okehampton on his patch and the results from that area made his hair stand on end. He moved on in a hurry before it fell out, I think. I don't think we got anything spectacular like that, but a few of them were followed up.
