All the news about north korea and iran lately have left me thinking about prepping for an atomic disaster. Sadly I know little. I doubt ill have the funds to sheild myself from radiation but if anyone has researched in this area advice would be appreciated. The only thing ive seen browsing around were some iodine tablets said to fill up you thyroid glad with clean iodine to prevent you from absorbing radioactive iodine which causes thyroid cancer. Specificly the info I would be interested in are good sound products that will help and time frames/techniques to avoid exposure.
