Talk:Bismuth-209

From Wikipedia, the free encyclopedia

I corrected the half-life figure by removing a decimal point. Two sources suggested a half-life of 19 exayears not 1.9 exayears. This was the edit of 16 september 2007.

How can you jump from that observation to the categorical statement that all Bi209 is unstable?
