Direct deposition of radioactive material onto crops is one important pathway for safety assessment of radionuclides released from nuclear facilities. Foliar uptake of Cs by radish (Raphanus sativus L. cv. Redchim) was studied by applying droplets of Cs solution (CsCl or CsNO3) on an upper leaf surface. The uptake of Cs was strongly affected by counter anions of Cs in the applied solution. Approximately 80% of Cs was absorbed for CsCl solution, while only 20% was absorbed for CsNO3. The partition of absorbed Cs between leaf and root tuber was quite similar for both Cs compounds, which indicated that behavior of the absorbed Cs in radish was the same for both.
放射性物质直接沉积到农作物上是核设施释放的放射性核素安全性评估的一个重要途径。通过将铯溶液（氯化铯或硝酸铯）滴在上部叶片表面，研究了萝卜（Raphanus sativus L. cv. Redchim）对铯的叶面吸收情况。施加溶液中铯的抗衡阴离子对铯的吸收有强烈影响。对于氯化铯溶液，约80%的铯被吸收，而对于硝酸铯，仅20%被吸收。两种铯化合物在叶片和块根之间吸收铯的分配情况非常相似，这表明萝卜中吸收的铯的行为对于两者是相同的。
