Re: Question about HI-PROPE

Dear Bob,
since your source particle is a radioactive isotope, you have to
activate the radioactive decay to get anything from your simulation.
This means that a RADDECAY card must be present as well as an
irradiation profile suitable with the lifetime of the isotope (Co-60 in
your case).
Hope this helps,

Lucia
