Do you have a nuclide chart hanging in your office or nearby? If so, you will know the usefulness of these 'collectors items' in which radionuclides are displayed according to the number of protons Z and neutrons N in their nucleus. In addition to giving the most important basic nuclear data, this arrangement, originally proposed by Segre, allows one to trace out decay and reaction paths qualitatively.

You will also be very aware that these charts are of limited use with regard to the amount of data that can be shown. More over, one invariably has to go a step further and make calculations with this data. Until now, the solution was to resort to large computer codes or if this takes too long, to write a computer program to solve the decay equations. Another possibility would be to have the calculations done by an expert.

These problems have now been overcome with the development of Nuclides 2000 [1]. With this new "Electronic" Chart, there is basically no limitation on the amount of data that can be stored and shown for any particular nuclide. More importantly, one can now do calculations quickly, reliably, using qualified data in a user-friendly environment. Tedious calculations are now redundant with this package. Through the Nuclide Explorer, the backbone of the Nuclides 2000 software, the user has access to powerful navigational, informational, and calculational interfaces. These allow fast identification of the particular nuclide(s) of interest, a summary of the basic nuclear and radiological data, and calculations using this data.
