I bought a bunch of the RADSticker's, Potassium Iodide (KI) Vial and Military M8 Chemical Detector and Identifier's from here. http://www.ki4u.com/products1.php
Like you said it's best to take the good/natural Iodine products first and the one's from that site as a last resort. We take two types of seaweed products already and have a several month supply.
Other than that, I'm keeping my mouth shut. Too discussed with MSM right now. :-)
