I'm sorry, but your subject matter expertise on terrorist's targeteering is based on what exactly?
Terrorism is based on ideas, messages, and perceptions.
Radiological weapons are very psychological. Using them successfully would allow the terrorists to say, "Hey world, look; we're capable of, and willing to, use nasty weapons....and your security services are unable to protect you."
The second- and third-degree effects of such an occurrence could be quite extreme.
Depending on the terrorist group's motivations, using a radiological weapon, even without mass casualties, could serve their purposes very well.

Ottawa quietly prepares for 'dirty bomb' attack

OTTAWA — A new federal study says the explosion of a small dirty bomb near the CN Tower would spew radioactivity over four square kilometres, resulting in mass anxiety, a rush on Toronto's medical facilities and an economic toll of up to $23.5-billion.
The nightmarish scenario — detonation of a device containing a modest amount of americium-241, a silvery plutonium byproduct — is among several sobering projections quietly mapped out by federal officials to prepare for a terrorist attack in urban Canada.
The study led by Defence Research and Development Canada also predicts economic costs of up to $8.75-billion should a similar americium-laden device be set off outside Vancouver's B.C. Place Stadium — a venue for the 2010 Winter Olympics — and as much as $2.25-billion if one exploded near the Ambassador Bridge between Windsor, Ont., and Detroit.
The grim outline is not far-fetched. A database of lost and stolen radioactive items compiled by The Canadian Press reveals that an industrial gauge similar to the device in the study was snatched by thieves in Red Deer, Alta., in June 2003.
Though later recovered, the gauge was missing for five days before its owners even noticed it was gone.
Two radiation safety experts consulted by The Canadian Press confirmed the device, used to measure oil wells, is a high-risk instrument that would pose a danger if the americium inside were successfully dispersed in an explosion.
The findings come mere months after the Canadian Security Intelligence Service said a dirty bomb assault was “overdue.”
