Dear @ceruttif
I am sorry that I could not understand the solution. Let me explain the situation with an example that I carried out.
The fluence considered = 1E+14.
Case 1: I considered a planar source of dimension 40 cm x 80 cm, area = 3200 cm^2, p/s = 3200 *1E+14. With this criteria, the activity of Mo in the output is 8.242E+13 Bq.
2nd case, planar source dimension is 40 cm x 40 cm, area = 1600 cm^2, p/s = 1600*1E+14. With this criteria, the activity of Mo in the output is 4.1268E+13 Bq.
In both the cases, all parameters are same except source dimension. I kept fluence value constant in both the cases, so I multiplied the source area accordingly into p/s term.
I have included the input files if needed. Am I missing anything about the unit of output of RESNUCLE? The manual said the unit is in Bq. Do I have to include any normalization in the output ?
