Estimation of the release time of radio-tellurium during the Fukushima Daiichi Nuclear Power Plant accident and its relationship to individual plant events

Takahashi, Sentaro*; Kawashima, Shigeto*; Hidaka, Akihide  ; Tanaka, Sota*; Takahashi, Tomoyuki*

A simulation model was developed to estimate an areal (surface) deposition pattern of $$^{rm 129m}$$Te after the Fukushima Daiichi Nuclear Power Plant accident, and by using this model, timing and intensity of the release of $$^{rm 129m}$$Te were reversely estimated from the environmental monitoring data. The validation using data for $$^{137}$$Cs showed that the model simulated atmospheric dispersion and estimated surface deposition with relatively high accuracy. The estimated surface deposition pattern of $$^{rm 129m}$$Te was consistent with the actually measured one. The estimated time and activity of $$^{rm 129m}$$Te emission seemed to indicate that the $$^{rm 129m}$$Te was emitted mainly from Unit 3.
