           Summary: Information on radioactive isotopes is out of date:
                    e.g. Bismuth is radioactive
           Product: kalzium
           Version: unspecified
          Platform: RedHat RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kalzium at kde.org
        ReportedBy: GavinFlower at yahoo.com


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.
