Tepco announced that a male worker in his 30s was exposed to high level of radiation. It is likely that he had a severe internal exposure too.
He was checking the water leakage around the water purifying system today.
He was externally exposed to 0.13 mSv/h gamma ray, 0.50 mSv/h beta ray.
After finishing his task, they found radioactive material attached to his jaw, neck and on mask.
They are going to have him tested by WBC.
