Abstract
Methods for dosimetry of epithermal neutron beams used in boron neutron
capture therapy (BNCT) have been developed and utilised within the
Finnish BNCT project as well as within a European project for a code of
practise for the dosimetry of BNCT. One outcome has been a travelling
toolkit for BNCT dosimetry. It consists of activation detectors and
ionisation chambers. The free-beam neutron spectrum is measured with a
set of activation foils of different isotopes irradiated both in a
Cd-capsule and without it. Neutron flux (thermal and epithermal)
distribution in phantoms is measured using activation of Mn and Au
foils, and Cu wire. Ionisation chamber (IC) measurements are performed
both in-free-beam and in-phantom for determination of the neutron and
gamma dose components. This toolkit has also been used at other BNCT
facilities in Europe, the USA, Argentina and Japan.
