In October 2006 , the Santa Susana Field Laboratory Advisory Panel , made up of independent scientists and researchers from around the United States , concluded that based on available data and computer models , contamination at the facility resulted in an estimated 260 cancer related deaths . The report also concluded that the SRE meltdown caused the release of more than 458 times the amount of radioactivity released by the Three Mile Island accident . While the nuclear core of the SRE released 10 times less radiation than the TMI incident , the lack of proper containment such as concrete structures caused this radiation to be released into the surrounding environment . The radiation released by the core of the TMI was largely contained
