Addressing Risk Perceptions of Low-Dose Radiation Exposure

Concern over low-dose radiation (LDR) (exposure of less than 100 milligray (mGy)) is resulting in people refusing diagnostic procedures and medical treatment¹ and also inhibiting revision of the linear no-threshold (LNT) assumption that informs much of science policy. This article reviews representative surveys in Ontario and Saskatchewan and focus groups conducted with science and policy stakeholders in addressing how the public and policy stakeholders understand issues of exposure to LDR and how policy issues can be addressed. Research results from focus groups demonstrated that policy stakeholders are knowledgeable about issues surrounding the public and perceptions about LDR and implications for policy consistent with LDR literature. Participants understood that the challenge went beyond providing more education about LDR and issues of emotions and biases must be addressed. This research resulted in rich suggestions for public communication and engagement surrounding LDR and a process for addressing the issue of the LNT.
