Thanks Ann, I'll look in to that as well, I have read anything from nano filtration to bacteria to take the ions out but no solutions, only promised upcoming technologies. I had gotten help from Sue at Cone Instruments to help get dosimeters to them over there and they have KI (Potassium iodide)finally over there now. It is kinda of ironic that I live within 100 miles of a nuclear power plant in Fla. and have a lot of equipment from floods to winter, etc.. but absolutely nothing for radiation. I figured if something went that bad, I probably wouldn't be alive to worry about it anyway. I may have to look in to KI pills down the road and a dosimeter after this matter. Our Crystal River plant is not the most kept up plant.
