Hi dear users
I want to get the scatter fraction and true and random rate so that I
can calculate parameter NECR.
I putted the phantom similar to the NEMA.
for example When I want to calculated NECR for 10 kBq/ml, the true rate
is much lower than the random rate.
Is this normal or is there something wrong with my simulation? 

Thanks in advance for any answers.
