Dear Konstantin,

Thank you very much for your prompt response.

However, I still have ambiguity while comparing the two results.

As you explained, if I multiply with the no. of primary (6.25E+13
protons/s) with the Dose scored using USRBIN(without specifying time),
it should match with the dose using DCYSCORE card (for zeroth time
decay). But, there is difference as illustrated follows in my problem.


Integral Dose by the USRBIN card for zeroth time decay(after 10 hr of
irradiation)is 9.97E+5 GeV/g/s. After scaling by total primary
(6.25E+13)the dose rate should be 1.59E-8 GeV/g/pr.
However, the USRBIN scored result is 8.77E-7 GeV/g/pr (without
DCYSCORE).

I would like to know the reason for discrepancy. whether I am missing
some factor ?


Regards
Ravi Rawat
