Three Mile Island and Chernobyl were not the only nuclear accidents in the last six decades. Were there any worse accidents (answer for both Three Mile Island and Chernobyl)?
What will be an ideal response?
There were incidents that led to release of activity, such as the Windscale fire in
October 1957 in the United Kingdom, which released an estimated 750 TBq (20 kCi). This
was worse than the Three Mile Island release of (17 Ci), but much less severe than
Chernobyl. However, during the cleanup, an additional 1.6 Ebq (43 kCi) of a krypton
isotope were released. making it worse overall than Windscale.
Other notable large-release accidents: A SNAP satellite explosion in 1964 released about
1.2 EBq (33 kCi) of radiation. In 1993, there was a 30 TBq release from a Tomsk, Russia
facility.
Nothing else accidental has outdone Chernobyl's accidental release. Following the last
answer is a list from Wikipedia of known nuclear release accidents.
