The meristems of Vicia faba bean roots were irradiated at different depths in water in a 250 GeV/c positive hadron beam from the CERN Super Proton Synchrotron (SPS). The growth during the 10 days following irradiation was determined and compared with results obtained from 60Co gamma-ray exposures. The data indicate a Relative Biological Efficiency (r.b.e.) near to one, independent of the contribution of secondaries to the dose. However, some anomalies in the radiation response of the irradiated beans were noted.
利用欧洲核子研究组织超级质子同步加速器（SPS）产生的250 GeV/c正强子束，在水中不同深度对蚕豆根的分生组织进行辐照。测定辐照后10天内的生长情况，并与60Coγ射线照射的结果进行比较。数据表明相对生物效应（r.b.e.）接近1，与二次射线对剂量的贡献无关。然而，注意到辐照蚕豆的辐射响应存在一些异常。
