Exactly 60 years ago today the USSR exploded a 57 megaton

toned down at the urging of the bombs designer Andrei Sakharov;
apparently even the communist thought 100+ megatons was a bit too
much. Russia recently released a documentary about it:
The largest H bomb ever exploded [1]

They replaced the U-238 tamper by a lead tamper to prevent radioactive
fallout. With the U-238 tamper the fast neutrons from the fusion
reactions would have induced fission of U-238 releasing another 50
megaton and also an enormous amount of radioactive fallout.
