ABSTRACT: The energy absorption coefficient of Cu-doped lithium potassium borate
(LKB) dosimeter and TLD 100 was reported theoretically and checked by
simulation of Monte Carlo n-particle code version 5 (MCNP5). The response of
LKB:Cu for various photon energies (20 keV to 10 MeV) were determined by
calculation, experiment and simulation. The obtained results were discussed and
compared with TLD 100. For more precise results, the geometry specification,
the source information, the material information and tallies were identified
and fully described. The results obtained by simulation were determined based
on the tally F6, which exhibited the response as energy-dependant on heating
function instead of flux. The current results showed that the prepared dosimeter
has a greater response than TLD 100 in the lower energy range and a flat response
in the higher energy ranges (≥100 keV).
