Dear FLUKA Experts,

While making a simple simulation for the calculation of dose at a receptor

at a distance 5 m below a line source of length 100 m , photon energy = 1

MeV, the Dose-Eq result from FLUKA output is 1.36E-05. Since the detector

size is taken as 10 cm radius of sphere, the actual dose-eq value for a

point detector will be 1.36 E-05 divided by volume of the detector (=

result is 3.246E-21 Sv per primary).

If the source is having an activity of 1 Bq/m, then the final result of dose

at a point below the line source is 3.246E-21 Sv multiplied by the length of

the source i.e. 100 m = 3.24E-19 Sv/sec . Since this is a standard simple

source configuration, the data can be obtained from the theoretical

calculation and the theoretical result is 3.5393E-17 Sv/sec.

Can you help me to point out why this discrepancy is occurring ??

With regards,

Riya Dey
