Acute γ-irradiation experiment was carried out in an experimental ecosystem model consisting of eight taxa of aquatic microorganisms. Various indirect effects due to interspecies interactions, some of which had not been known in aquatic microbial community, were detected. It was also demonstrated that radiosensitivity was different with cultural stage. These results will contribute to improvement of current frameworks for radiation protection of the environments. Effect doses of γ-rays and various chemicals were evaluated for the entire system. This result will contribute to a better understanding of environmental risks of ionizing radiation compared with chemicals.

急性γ辐射实验是在一个由八个水生微生物分类群组成的实验生态系统模型中进行的。检测到由于种间相互作用引起的各种间接影响，其中一些在水生微生物群落中尚不清楚。也证明，文化阶段的放射敏感性不同。这些结果将有助于改善当前环境辐射保护的框架。对整个系统评估了γ射线和各种化学品的效应剂量。与化学物质相比，该结果将有助于更好地理解电离辐射的环境风险。
