Abstract
Knowledge of the basic parameters of the BNCT epithermal neutron beam is one of the essential conditions ensuring the beam optimal therapeutic use. It is necessary for us to have appropriate tools for determining the beam geometry, absolute values of the dosimetry quantities and spectral characteristics for both neutrons and gamma rays. As far as the Czech BNCT project1 is concerned, the following set of the detectors is used:
-
the beam geometry—the radial and angular distributions of the beam: Semiconductor detector with natural Li converter—thermal and epithermal (with Cd) neutrons, 238U and 232Th fission chambers—fast neutrons Semiconductor detector—gamma rays
-
the dosimetry values of the beam: Activation foils—the fast, epithermal and thermal neutron fiuence rates, neutron spectrum, Bonner spheres—the fast, epithermal and thermal neutron fluence rates, neutron spectrum, Al-P glass TLD—the gamma absorbed dose,
-
Spectral beam values: Scintillation spectrometer—the fast neutron spectrum Hydrogen proportional spectrometer the fast neutron spectrum Scintillation spectrometer—the gamma ray spectrum
