The Real Data and Facts on radiation and Fukushima
"The first 'type' of radioactive material is the uranium in the fuel rods," wrote Dr. Oehmen, "plus the intermediate radioactive elements that the uranium splits into, also inside the fuel rod (Cesium and Iodine). There is a second type of radioactive material created, outside the fuel rods. The big main difference up front: Those radioactive materials have a very short half-life, that means that they decay very fast and split into non-radioactive materials. By fast I mean seconds. So if these radioactive materials are released into the environment, yes, radioactivity was released, but no, it is not dangerous, at all. Why? By the time you spelled "R-A-D-I-O-N-U-C-L-I-D-E", they will be harmless, because they will have split up into non radioactive elements..."
It takes about five seconds to spell R-A-D-I-O-N-U-C-L-I-D-E and it takes about the same amount of time to read a chart (below) which shows the actual lifetimes and half-lives of radioisotopes that people need to be concerned about today.
Not only does Dr. Oehmen intentionally misinform people about the inherent design flaws and potential failures of nuclear reactors and subsystems, but he knowingly disinforms about the potential for serious health consequences and the radioactive contaminants that are typically released during a nuclear power accident. While millions of people in Japan are suffering the personal psychological terror of a possible nuclear holocaust, the fears and horrors of life and death from a natural disaster, starvation and thirst, and radioactive poisoning. Dr. Joseph Oehmen -- safe in Boston Massachusetts -- has been been boasting about his blog post -- equally popular with people who hate it and love it -- which spread like a virus on the Internet.
During nuclear fission, the uranium from the fuel rods splits into many radioactive fission products that can then escape during a nuclear power 'event'. These include dangerous Noble Gases (xenon and krypton); Hallogens (including iodines and bromines); Alkali Metals (including cesium 137); Alkaline earths (including barium 133 and strontium 90) and the elements Tellurium and Ruthenium. Some fissionable elements decay rapidly and are inconsequential during releases, but some decay into other, more deadly nuclides. The most dangerous nuclides have half-lives in days (I-131 = 8 days), years (Cs-137 = 30 years) or centuries (Pu-239 = 24,000 years). Half-life is the time it takes for one-half of the material to decay -- lest we forget that the other half is still present.
