Since the last decades of the 19th century, a regulatory paradigm modeled on bureaucracy, legalization, and scientism was established, which has contributed significantly to the acculturation and normalization of risky technologies. Not only/just since the 1970s has the promise of security and certainty been dismantled via scientification as a fiction of rationality. The contributions to this volume touch on perceptual, interpretive, and regulatory models of high risk technology as well as structures of risk and catastrophe management in the ultramodern with examples from the railroad and chemical industries as well as nuclear energy.
