Re: info about DLRDCY

Hi Francesca,

I am not sure if DLRDCY is the right variable. In general, the age of the
currently transported particle is carried by ATRACK. I have never printed
it for radioactive decay products myself, thus don't know exactly which
point in time age=zero refers to. Please try yourself and post any
observation in case it doesn't make sense. Also try to run in
semi-analogue mode (RADDECAY/What(1)>1) and see if it makes a difference.

Just one observation in your input: your irradiation profile includes
2400sec with zero intensity. Please note that the decay time (as defined
with DCYTIMES) refers to the end of the irradiation profile which does
include the mentioned 2400sec. No problem if this is what you want.

Cheers,
Stefan
