    This thesis outlines results from an investigation of radon and radon daughter
    concentrations in limestone caves, from a geographical and geological perspective
    Investigations were conducted at all geographical scales, ranging from a national
    investigation in the four major caving regions of England and Wales to a detailed survey
    within a single cave in the Peak District.

    The measured radon concentrations in some limestone caves in England and Wales are
    amongst the highest ever recorded in the world Significant spatial and temporal
    variations were recorded m concentrations at all scales, within a single cave, between
    caves in the same region and between different regions Additionally, seasonal and
    diurnal variations in concentrations were highlighted. External climatic variables and the
    cave radon budget were demonstrated to account for variations in cave radon

    Within limestone caves seven primary sources of radon were identified and the relative
    importance of each to the overall radon budget was determined Sediments and the
    contaming limestone rock were the major sources although in certain cases water and the
    soil were demonstrated to be influential

    Models were developed to predict cave radon concentrations within a single cave
    However, these could not be transposed to predict radon concentrations in other caves in
    the same region or other regions

    The users of limestone caves were identified, their potential exposure times were
    examined and legislation concerning their exposure was discussed Four groups were
    identified as being at risk from radon while underground, and three groups were
    identified as bemg at little risk Methods by which the risk from radon exposure can be
    reduced were examined
