Frank Brown of the Derbyshire Caving Club unfortunately died recently of lung cancer. He was a smoker and was fairly old but it did get me thinking about radon. As some of you may know Frank spent much of his later years digging in Nettle Pot. The environment down there iat the blind end of a series of deep shafts with little ventilation would be ideal for the accumulation of radon. The Block of limestone in which Nettle sits is known to be high in radon and I've seen some figures for some caves in the area which look high. The risks are not easily quantified but there is a possible case for saying that radon might have contributed to his illness. In the case of miners who spend far longer underground. cumulatively, it seems possible that active ventilation would disperse the gas. The normal situation in mines would be drilling which gives rise to high air flows, blasting and ventilation plus use of shafts, trains etc in material and personnel movement would prevail.
