John is more or less correct, dirty bombs are little more than a panic attack, as for the Iodine, hmm from what I've dug up, I should HOPE there is
radio-active Iodine (I-131), it seems to be fairly helpful in aiding the treatment of hyperthyroid (some ailment) and does not promote cancer.
And I think your half-life information is wrong, apparently after treatment (done at home by drinking it) it can collect in your bladder (the
radio-active materials) so you have to drink a lot of fluids for several weeks to wash it all out.
Hmm doesn't seem like Iodine is a threat Tyler
