Some radiation was released when the pressure vessel was vented. All radioactive isotopes from the activated steam have gone (decayed). A very small amount of Cesium was released, as well as Iodine. If you were sitting on top of the plants’ chimney when they were venting, you should probably give up smoking to return to your former life expectancy. The Cesium and Iodine isotopes were carried out to the sea and will never be seen again.
圧力弁が解放されたときにいくらかの放射線物質が放出された。放射化した蒸気による全ての放射性同位体は無くなった（崩壊した）。ごく少量のセシウムとヨウ素が漏出した。もし蒸気放出時にあなたがプラントの煙突のてっぺんに座っていたのなら、あなたは、元の寿命を回復するために禁煙しないといけないかもしれない。セシウムとヨウ素同位体は海に運びだされ、二度と出会うことはないだろう。
Below 100 to 500 mSv is thought to be safe according to the National Institute of Radiological Sciences (放射線医学総合研究所)
