"Fusion of Horizons": Part II. Modernizing radon regulation (1954–1993)

This part of the article explores the transformation of radon regulation between 1954 and 1993, a period marked by significant advancements in scientific understanding and public health policy. It examines the shift from occupational to residential radon exposure concerns, the integration of epidemiological data into regulatory frameworks, and the emergence of international standards such as ICRP 65. By analyzing this changes through Gadamer's hermeneutic concept of “fusion of horizons,” the study underscores how evolving scientific insights and social expectations redefined the approach to radon as a public health challenge. This part highlights the milestones that bridged the gap between early regulatory attempts and comprehensive modern frameworks.
