Pretty sure. You did notice the 1,000,000 Ci of noble gases, right? Jim Hardeman >>> Mike McNaughton 05/12/97 12:06 >>> > ... and radioiodine releases (predominantly I-131) of about 12 Ci. Are you sure about the I-131? A large amount of I-131 was released at Chernobyl, but I believe this was not the major radionuclide released at TMI.
