| Outline of Final Research Achievements |
Radioactive tellurium were released to the environment along with radioactive cesium and radioactive iodine as a result of the accident at the Fukushima Daiichi Nuclear Power Plant. Te-127m may have moved from soil to foodstuffs and been ingested by local residents. However, little is known about soil retention and transfer from soil to plant of Te in the ecosystem.
In this study, the transfer factors from soils to plants were determined for stable Te and Cs in radish and komatsuna. The ratios the committed effective doses for radioactive Te to radioactive Cs calculated with the transfer factors indicated by this study are two orders higher than those calculated with the transfer factors reported by IAEA. This result indicates that there is a possibility that the actual committed effective dose from the ingestion of radioactive Te is considerably lower than the dose calculated with the transfer factors of reported by IAEA.
