Oh, I don't know. My daughter and son-in-law were buying a brand-new house built on Limestone, in the lowest possible area for radon exposure, but because of the surveyor's remarks they could not get a mortgage until they had paid for a full survey by the radiological protection board. None of the adjoining properties had to, it was entirely down the the surveyor 'dealling in things that don't exist'.
