"Cumulative Low-Level Doses of Radiation Can Cause Big Problems"

As the "experts" continue to try to keep everyone calm and the nutcases on the net troll every article talking about how "tiny" picocuries are...they all ignore the difference between INTERNAL and EXTERNAL exposure, they ignore the bio-accumulative effects as it enters the entire food chain and water (in which we shave, bathe, shower, and all other drinking substances and most foods are made daily...multiple times per day), and they ignore everything other than the shortest half-life material of I-131 when they should also look at Cesium, Plutonium, Xenon, Tellurium, and Strontium among others. How can "experts" and their mindless followers ignore all of that??? These exposures are not going to be one-off deals, they are continual and repeated exposures for months to come and possibly years.
