Dear Fluka experts,
I am studying the activation of the air surronding a D-T neutron generator, inside (INPU region) and outside (INSHIEL region) the primary polyethylene/graphite shield. I have set the essential cards for activation, including PHYSICS, IRRPROFI, DCYTIMES, RADDECAY, RESNUCLE and DCYSCORE. Currently, I am interested to obtain Bq/cmc at t=0 after 3 hours of irradiation with a primary beam of 2e8 n/s.

I have two questions:
-
Even if I ran a simulation of 5e8 histories, the relative percentage error printed in sum.lis and tab.lis files is 99% for all radionuclides produced in both regions. These uncertainties make the result meaningless. What could be wrong? I would be expected lower uncertainties in the inner region (INPU) because there the activation events should be more likely.

Is it possible to plot RESNUCLEI in 2-D diagram to see, for example, the location where the production of a radionuclide take place?
Thank you
