Re: Chernobyl spent fuel

[Peter Aryasov <aryaspin@RPI.KIEV.UA>]

Fritz,



James is right - the biggest FCM is the so-called "elephant's foot", and there

are several smaller

FCM at different floors of the Shelter, mainly under the reactor. Another

famouse

FCM (smaller then "El foot") called "the drop". As I know the gamma background

near the "El. foot" is about 1500 Roentgen.



Best regards, Peter
