| Outline of Final Research Achievements |
This study aimed to establish an evaluation method of the health effect of internal exposure with radioactive iodine both in vitro and in vivo. Cultured cells isolated from rat thyroid showed several responses to influx of I-131, including cell survival, DNA damage/repair, and signal transduction, in a different manner from that to external exposure with Cs-137 source. Although the SPECT imaging of mouse thyroid was possible by I-131, the quantitative detection of internal exposure for health risk assessment needs further development using additional radio-probes. These results were preliminary but effective in risk communication situation with residents.
