Abstract
Tissue equivalent proportional counter microdosimetry has been applied
in the dosimetry of epithermal neutron beams as they can provide an
independent and accurate method to determine gamma ray and neutron
absorbed doses. Dosimetric comparison has been performed using a tissue
equivalent proportional counter, dual ionisation chambers and DORT
computer code at FiR 1 boron neutron capture therapy facility in Espoo,
Finland. The three methods were applied to determine neutron and gamma
ray absorbed doses at 25, 40, 60 and 120 mm depths along the beam
centerline in a water-filled PMMA phantom. The determined absorbed doses
were found to agree within the limits of the estimated uncertainties.
