# The result of USRBIN

Dear experts,
I want to know what is the mean of the “integral value” in the result of USRBIN when I choose different “WHAT(2) in USRBIN such as “NEUTRON,DOSE,ENERGY””?
And, when I choose “NEUTRON” in USRBIN , I can get neutron fluence in the result ,but I can not understand the unit of it well, dose it mean the fluence at a certain point in space?

Dear @Junjie_Zhang,

For the meaning of the results of the USRBIN card have a look at the scoring lecture:

and at the corresponding manual page: USRBIN | FLUKA
