Beta+ decay||Predicting the mode OF decay

In a beta -decay

In beta- decay, all the emitted electron do not have the same energy the same energy. beta- decay is not a two body decay process.

._(92)U^(238) changes to ._(85)At^(210) by a series of alpha -and beta -decays. Find the number of alpha -decays undergone ("an integer") .
