Description Gavin C. Flower 2009-10-25 07:27:03 UTC

Version:           2.2.98 (using KDE 4.3.1)
OS:                Linux
Installed from:    RedHat RPMs

Description of problem:
There are a least 2 isotopes described as stable, but have been found to be
unstable within the last 6 years.

Bismuth 209 has a half life of about 10^19 years
http://physicsworld.com/cws/article/news/17319

Tellurium 128 has a half life of about 10^24 years
http://ie.lbl.gov/toi/nuclide.asp?iZA=520128

Version-Release number of selected component (if applicable):
2.2.98

How reproducible:
Always

Steps to Reproduce:
1. Select  Bi, Te
2. Check list of isotopes
3.

Actual results:
stable

Expected results:
should give half lives

Additional info:
These isotopes generate far less radioactivity than you would normally get from background radiation in everyday life.  

It would be safe, even if silly, to go
around carrying a kilogram of the stuff in terms of radioactive exposure.

The estimated age of the universe is 14 billion years, only about 1.4e10. So these are theoretical lifetimes incomprehensibly greater than the age of the universe. I think it's fair to call them 'stable' and leave it as is. It might be interesting to add another setting that lists theoretical lifetimes when a user clicks.
