Radioactive decay Physics Nuclear physics
Decay.JPG


Overview:

A simulation illustrating radioactive decay.

The table shows some isotopes.

Choose an element and check whether it is stable or not.

If it is unstable, wait a few seconds and it will decay.


Suggestions:

Discuss the stability of various isotopes.

Discuss lifetimes and energy releases.

Why do some decay schemes go "upwards" and others go "downwards"?

What does this mean for B11, for instance?

Find decay sequences in the table.
