Greg,
Thanks for the words on dirty bombs and KI. Half life statement was concerning the unlikely scenario of an actual blast, and probablity of small blast area - not talking multiple warhead ICBM's here but suitcase situation. Also, I don't live in town but on the furthest outskirts and am assuming that the major buildings downtown would be the high visibility targets for maximum media exposure. Agree that dirty bomb is more likely, and greatly appreciate the info. My greatest concern is being in the car in a fallout situation or high rad exposure. Assuming some distance from the incident, would prefer to have some roofing and concrete walls around me until the authorities advise otherwise. Regards, Keys
