Letter Chair Onshore Oil & Gas: In his letter Dr David Lowry raised the issue of radon and shale gas quoting studies in Pennsylvania and sought to reinforce his own views by quoting from a study undertaken by Public Health England in 2014. Let me quote the same study, which states, “caution is required when extrapolating experiences in other countries to the UK since the mode of operation, underlying geology and regulatory environment are likely to be different” and “the PHE position remains, therefore, that the shale gas extraction process poses a low risk to human health if properly run and regulated”. Radon is a naturally occurring radioactive gas present throughout the UK at very low levels. PHE recognised that radon may be released to the environment from shale–gas activities, as is the case with existing natural gas supplies, but at concentrations that are not expected to result in significant additional radon exposure.
