The experiment was carried out on lattice (Lactuca sativa) seeds flown in a biocontainer equipped with plastic detectors to record heavy charged particles (HCP). The purpose of the experiment was to determine the yield of aberrant cells as a result of irradiation, and to identify this effect as a function of HCP topography in the seed. The cytogenetic examination of flight seedlings revealed a significant difference between the seeds which were hit with HCP and those that remained intact. This indicates a significant contribution of the heavy component of galactic cosmic rediation into the radiobiological effect. The relationship between the radiobiological effect and the HCP topography in the seed was established: zones of the root and stem meristema proved to be most sensitive targets.
该实验使用搭载在配备塑料探测器的生物容器中的生菜（Lactuca sativa）种子进行，以记录重带电粒子（HCP）。实验目的是确定辐照导致的异常细胞产量，并将这种效应确定为种子中HCP拓扑结构的函数。对飞行幼苗的细胞遗传学检查显示，受到HCP撞击的种子与未受影响的种子之间存在显著差异。这表明银河宇宙辐射的重成分对放射生物学效应有显著贡献。建立了放射生物学效应与种子中HCP拓扑结构之间的关系：根和茎分生组织区域被证明是最敏感的靶点。
