(Natural News) The environmental disaster that was caused by the Fukushima-Daiichi nuclear power plant accident continues to persist, even today. While the mainstream media continues to push the belief that everything is just fine and dandy — this simply isn’t the whole truth.
Migratory fish, specifically bluefin tuna and albacore tuna, have tested positive for two radioactive isotopes that were released in the wake of Fukushima. While the National Oceanic And Atmospheric Administration claims that the levels of Cesium 134 and Cesium 137 found in these fish are “far and below levels that are considered cause for concern,” one just has to wonder: what about the other radioactive isotopes that were released? How can they be so sure that these isotopes, at any level, have no potential for harm? And how do we know that this situation isn’t going to get worse?
Understanding radioactive isotopes
The two isotopes that have been declared present in West Coast fish are Cesium-134 and Cesium-137. Cesium-134 has a half-life of about two years, while Cesium-137 boasts a half-life of 30 years. The half-life is the rate at which a radionuclide breaks down to half its original atoms. The half-life is a time-based measurement that can appear in any increment from seconds to millions of years. This is important because it allows us to understand how long radioactive substances can persist in the environment.
The concern with these isotopes particularly in fish is the ability of Cesium-137 to accumulate in the tissue of fish, and potentially cause tissue accumulation of the radioactive isotope via consumption.
One thing that is rather interesting about this recent research is that there was no testing done for Strontium-90, another radioactive isotope that was released by the Fukushima accident. Strontium also has a lengthy half-life, of about 28 years. (Click to Article)
