In this input, without DCYSCORE, the DOSE-EQ values are generated in the output, but while using DCYSCORE associated with different cooling time, the output is zero. It will be helpful if you can kindly guide. Same can be observed for RESNUCLE output.
There is a substantial difference and the result unit is not the same.
Without DCYSCORE, there is no irradiation parameter involved at all, one gets the nuclide production yields, namely number of nuclides per primary beam particle, produced during the prompt irradiation stage, with no reference to time.
With DCYSCORE, one gets the nuclide activity in Bq at a given cooling time, as a function of the input irradiation profile.
Please note that this does not apply if radioactive decay is requested in semi-analogue mode: no cooling time shall be input in this case and RESNUCLEi, coupled to a DCYSCORE card that asks to include daughter nuclides, will still give production yields. See the linked discussion.
