The radiobiologic characteristics of 15 MeV neutrons produced by the d + T reaction at the TNO of Rijswijk and of neutrons produced by the d(50) + Be and p(75) + Be reactions at the cyclotron Cyclone of Louvain-la- Neuve were compared. Growth inhibition in Vicia faba bean roots was used as biologic system. An OER value of 1.5 +/- 0.1 ws obtained for the neutron beams compared. The RBE of 15 MeV, d(50) + Be and p(75) + Be neutrons was found equal to 3.4 +/- 0.2, 3.2 +/- 0.2 and 2.9 +/- 0.3, respectively, relative to gamma rays, for a total (n + gamma) absorbed dose of 0.6 Gy.
比较了在赖斯韦克的荷兰应用科学研究院（TNO）通过d + T反应产生的15 MeV中子以及在鲁汶新堡的回旋加速器“旋风”中通过d(50) + Be和p(75) + Be反应产生的中子的放射生物学特性。以蚕豆根的生长抑制作为生物体系。所比较的中子束的氧增强比（OER）值为1.5±0.1。相对于γ射线，对于总（n + γ）吸收剂量为0.6 Gy的情况，发现15 MeV、d(50) + Be和p(75) + Be中子的相对生物效应（RBE）分别等于3.4±0.2、3.2±0.2和2.9±0.3。
