The Role of Qualitative Risk Assessment in Environmental Management: A Kazakhstani Case Study

| March 2012

Successful environmental management is partly contingent on the effective recognition and communication of environmental health risks to the public. Yet risk perceptions are known to differ between experts and laypeople; laypeople often exhibit higher perceptions of risk in comparison to experts, particularly when these risks are associated with radiation, nuclear power, or nuclear waste. This paper consequently explores stakeholder risk perceptions associated with a mercury-contaminated chloralkali production facility in Kazakhstan.

Reducing Nuclear and Radiological Terrorism Threats

| July 2007

Urgent actions are needed to prevent a nuclear or radiological 9/11.  Terrorists are actively seeking nuclear weapons and Radiological Dispersal Devices (RDDs) and the materials to make them.  There are scores of sites where the essential ingredients of nuclear weapons exist, in dozens of countries worldwide.  There are thousands of sites worldwide where radiological materials exist.  Many of these sites are not sufficiently secured to defeat the kinds of threats that terrorists and criminals have demonstrated they can pose.  A dangerous gap remains between the urgency of the threat of nuclear and radiological terrorism and the scope and pace of the U.S. and world response.  While the gap has narrowed significantly in recent years, much more needs to be done.  This paper describes the nuclear and radiological terrorism threats, analyzes the actions taken so far to address these threats, and recommends further actions going forward.
