Experimental irradiation setups. Setups for biological sample exposure to X-rays (a) and to the mixed neutron – photon field (b) at RARAF. The photon beam is perpendicular to the flask surface, the dose rate is of ~1.1 Gy/min. In the mixed field, neutrons (average energy of 2.4 MeV, maximal energy of ~10 MeV, energy distribution referred to as Hiroshima neutron spectrum) and photons are generated by a primary 5 MeV mixed proton and deuteron beam impinging onto a Be foil. Flasks are secured to the rods of a metallic wheel, rotating around the primary beam axis, and positioned at a forward angle of 60° and at a distance of 10 cm from the 9Be target. The dose rate is of ~0.05 Gy/min, neutrons account for ~83% of the total dose in the mixed field.
