On June 5th, however, the same military organisation that had only weeks before considered this incident to be very serious, suspended Operation SMOKE STACK until more information could be brought forward as to the possible whereabouts of the two missing Cesium 137
radioactive isotope containers.
Nuclear experts have identified cesium 137
as being inside a sealed container imported last week from the Philippines that was found to be emitting radiation, the Science and Technology Agency said Monday.
is attempting to create a commercial demand for cesium 137
, a byproduct of plutonium extraction that can be used as a source of gamma rays in food irradiation plans.
In a separate incident, two workers at Hanford were being checked for radioactive cesium 137
According to the study, cesium 134 and cesium 137
found in 15 bluefin tuna caught off the coast of San Diego, California, last August measured 4 bequerels per kilogram and 6.
The most significant release of radiation at Chernobyl involved two by-products of uranium fission - Iodine 131 and Cesium 137
In 1993, lab officials found elevated levels of tritium, along with strontium 90, cesium 137
and plutonium 238, in soil samples from Brandies Bardin taken near the lab property line.
Among the radiation sources used in the testing were plutonium, enriched uranium, cesium 137
, barium 133, phosphorus 32 and combinations of these sources.
