 note = {Neutron exposure Accelerator System for Biological Effect Experiments (NASBEE) is installed for research on the biological effects of fast neutron at the Low Dose Radiation Effects Research Building in National Institute of Radiological Sciences (NIRS). Biological researches, which observe neutron RBEs (Relative Biological Effectiveness), are important for radiation protection around several nuclear facilities and accelerators. This system is a 2 MV tandem electrostatic accelerator (high current coaxial tandetron), equipped with the multi-cusp ion source, which generates high current 4 MeV deuteron beam with maximum current of 0.6 mA. This accelerator produces the largest beam current over the world in this accelerator classes. Neutron beams are produced by bombarding deuteron in a thick beryllium target with 3 mm in thickness, cooled with a stream, and the neutron energy spectra are broad from thermal to 10 MeV neutrons. In addition, highest dose rate is approximately 2.0 Gy/hr with relatively low contamination of gamma-rays (< 17 %). Another characteristic of this facility is that there are two irradiation ports. One is in the SPF (Specific Pathogen Free condition) room where in vivo irradiation experiments using mice and rats can be carried out. Another room is for physic experiments and in vitro experiments using mammalian cells. In the present study, we will show the dose rate, irradiation field, and its dose distribution, LET spectrum in detail, along with the preliminary results on in vitro experiments., The 2nd Asia-Pacific Symposium on Radiation Chemistry},
