[Nuc 1.1]

Good post. Mostly accurate.

[SAJ]

For those of us who are not engaged in nuclear physics and found the good doctor's commentary very clear and informative, could you please elabourate on any inaccuracies.

Also, what is the half-life of the radioactive isotopes of iodine and cesium to which the doctor refers? These numbers did not appear in the article (or, perhaps I just missed them). These would seem to be somewhat of importance, as radioactive cesium is oftentimes mentioned as the principal nasty agent in a (putative) terrorist dirty-bomb attack.

Thank you for any corrections/information you can add, and FReegards!
