Abstract
United States Atomic Energy Commission (USAEC) and UN agencies utilized techniques of power and negotiation to implement radiation exposure regulations. USAEC affiliated scientists' expertise was cultivated while establishing a radiation protection regime based on classified experiments. World Health Organization (WHO) leadership sought to manifest a human right to health, including a right to protection from radiation contamination. The careers of a few technical experts and interagency UN correspondence shows how American risk models of radiation regulation traveled and ultimately inhibited WHO attempts to frame radiation as a public health threat. The USAEC and the International Atomic Energy Agency (IAEA) navigated WHO's way of perceiving radiation with technical experts and bureaucratic and legislative means. This paper shows the underpinning at the UN of competing models of radiation regulation, one state centric and the other, an individual right to health. This narrative provides insights into the nature of the UN's current conceptualization of radiation regulation and argues for further research into UN, radiation, and human rights history.
