Nuclear Terrorism Post-9/11: Assessing the Risks

This paper discusses, with an emphasis on the technical issues involved, some of the possible forms that nuclear terrorism might take, loosely referring to all forms of terrorism involving radioactive materials, such as crude nuclear weapons, radiological dispersal devices, and attacks on the nuclear infrastructure, including nuclear reactors. The first two forms of terrorism necessarily depend on terrorists' obtaining suitable materials, so the problem of nuclear smuggling, especially from the former Soviet Union (FSU), with its huge and decrepit nuclear complex, is addressed, as is the region's reservoir of unemployed or underemployed nuclear expertise. The West, however, is not ignored. As one observer remarked, Osama bin Laden might soon have more luck shopping for nuclear materials there than in the FSU. The paper concludes that although it is most unlikely that terrorists will detonate a true nuclear weapon, the other forms are real and pressing threats.     

The New Forest Suicide Prevention Initiative (NFSPI)

A retrospective suicide study revealed that the Forestry Commission car parks in the New Forest in southern England were a previously unrecognized magnet for nonlocal suicides, attracting as high a proportion of "visitors" (35/43 in 1993-97) as among suicides who jumped from the cliffs at the infamous Beachy Head (39/48 in 1993-97). Over 95% of the car park suicides died from car exhaust gas poisoning. A multiagency initiative aimed to reduce the number of suicides in the 140 New Forest car parks where restricting access was impossible, and environmental issues paramount. Signs displaying the Samaritans' national telephone number were erected in the 26 car parks in which 50% of the car park suicides had occurred. Numbers, location, and residence of all car park deaths were monitored for 3 years. Corresponding changes in other forest registration districts were also monitored. During the 3-year intervention period the number of car park suicides fell significantly from 10/year, 1988-1997, to 3.3/year. The average annual total number of suicides in the New Forest registration district also decreased. No significant changes were found in comparable forest districts. The number of suicides in the New Forest car parks remained low during the 2 years following the evaluation.
