The release of 137Cs is estimated to be 85 PBq, equal to about 30% of the amount in the reactor core, and that of 131I is estimated to be 1,760 PBq, about 50% of the core inventory.
It was the most significant accident in the history of the American commercial nuclear power generating industry, resulting in the release of up to 481 PBq (13 million curies) of radioactive gases, but less than 740 GBq (20 curies) of the particularly dangerous iodine-131.
(1.59 PBq) of radioactive krypton gas, but less than 20 curies (740 GBq) of the especially hazardous iodine-131, into the surrounding environment.
This loss of coolant accident resulted in the release of a significant amount of radioactivity, estimated at 43000 curies (1.59 PBq) of radioactive krypton gas, but less than 20 curies (740 GBq) of the especially hazardous iodine-131, into the surrounding environment.
In October of 1957 the Windscale facility, as it was called then, was the location of a nuclear accident which allegedly released the following inventories of radioactivity to the environment: 0.7 PBq 131I; 0.04 PBq 137Cs; 4 TBq 89Sr and 0.3 TBq 90Sr
