Dear Agnieszka,
could you be more specific why the results are not correct?

I ran your Co60 input after having added a USRTRACK to score also photon fluence.
And I see the two photon peaks at 1.17 and 1.33 MeV.

The low energy electrons are not transported to the scoring region because of transport threshold that is
100 keV since you used PRECISIOn as DEFAULTS (it is recommended to set explicitly its value with EMFCUT, which is not present in your input).

Cheers, luigi

I used USRTRACK card and scored electrons in the target, however I obtained really "strange" results not looking like spectrums of the requested isotopes. Can You please advise what is wrong in my inp files and why I cannot get correct results?
