Abstract
A research group to carry out clinical application of
BNCT was established in Finland in the early 1990's. The
neutron irradiations will take place at the Finnish
research reactor (FiR 1) operated by VTT in Otaniemi. In
April 1996 the new FLUENTALtm neutron moderator
developed by VTT was installed and in September a conical
beam collimator. Neutron field and dosimetric
measurements have confirmed that the epithermal neutron
field is suitable for human treatments. In October a
thorough renovation of the reactor building has started.
The ground and first floor will be converted into a BNCT
research and treatment facility.
The Monte Carlo based INEL NCT dose planning program
rtt_MC has been used in the determination of the brain
substitute materials for head phantoms. The program is
also used in the healthy tissue tolerance studies. Other
efforts in dosimetry include studying the suitability of
TL detectors for BNCT.
To determine the boron capture dose distribution the
boron distribution in the tumour and in the other tissues
has to be known in addition to the thermal neutron
field. The current efforts on boron bulk-analysis are
focused on the methods ICP-AES, PGNA and PIGE. In order
to analyse boron distribution at cellular level SIMS will
he used combined with freeze-drying and cryosectioning,
thus preserving the original boron distribution in the
samples. Boron distribution determination in vivo is
pursued by radiolabelling boron carriers.
Normal tissue tolerance studies in co-operation with CRC
Radiobiology Unit, Oxford, England, will contribute
towards the verification of the treatment planning,
radiation doses, biological effects and radiation safety
of BNCT before proceeding to therapies of patients. Boron
carrier biodistribution studies of boronophenytalanine
(BPA) will be completed in 1998, with data available for
the patient treatments.
