セシウムでの健康被害は報告されていないから安全といまだに言い続けている専門家の人は、米国に対しても『風評被害』をマスメディアを介して与えていることになることを気づくべき。たとえば相手は米環境保護庁になりますが、大丈夫?http://t.co/NlCLL0M

Walking on cesium-137 contaminated soil could result in external exposure to gamma radiation. Leaving the contaminated area would prevent additional exposure. Coming in contact with waste materials at contaminated sites could also result in external exposure to gamma radiation. Leaving the area would also end the exposure. If cesium-137 contaminated soil becomes air-borne as dust, breathing the dust would result in internal exposure. Because the radiation emitting material is then in the body, leaving the site would not end the exposure. Drinking cesium-137 contaminated water, would also place the cesium-137 inside the body, where it would expose living tissue to gamma and beta radiation.
