WebChernobyl compared with the Goiânia accident. While both events released 137 Cs, the isotopic signature for the Goiânia accident was much simpler. It was a single isotope which has a half-life of about 30 years. To show how the activity vs. time graph for a single isotope differs from the dose rate due to Chernobyl (in the open air) the following chart is shown …
