| 内容記述 | A massive earthquake and tsunami on March 11, 2011, resulted in the release of an enormous amount of radioactive materials into the environment. On the day after the earthquake the Japan Atomic Energy Agency (JAEA) began emergency radiological monitoring. Measurements with a whole body counter (WBC) for the staff members who had returned from Fukushima began at the end of March because a power blackout for several days and lingering increased ambient radiation levels had rendered the WBCs inoperable. The measured activity level for I-131 due to inhalation for emergency staff varied from below detection limit to 7 kBq, which corresponds to an estimated initial intake range of <1 to 60 kBq when extrapolated back to the date the staff began the monitoring in Fukushima. The measured activity levels for Cs-134 and Cs-137 were both in the ranges from below detection limit to 3 kBq. When using the median values for each set of measurements, the ratio of the initial intake of I-131 to Cs-137 was 11. The maximum committed effective dose of 0.8 mSv was recorded for a member of the 4th monitoring team dispatched from March 15 to 20. | |||||
