Description
Neutron flux produced from a LINAC made by Toshiba company was measured using fission track spark counting method. This LINAC is used for X or electron irradiation for medical use. The detectors were Makrofol KG polycarbonate films 10 μm thick, which were attached with thorium or uranium targets and were kept in the neutron field. Fast neutron flux in the room were distributed up to 6 x 106 n/cm2·sec. The mean value of that at the irradiation area on the patient was 4 x 107 n/cm2·sec. Thermal neutron flux at the surrounding wall was larger than that at the centre of the room. Thermal neutron was not detected near the irradiated area. (author)
