Following up this article..130μSv/h in Minamisoma
In Minamisoma, where the highly radioactive black substance was found, seasonal wind is blowing from the west.
Hot particles are taken into lungs, eyes and ears cause serious internal exposure.
This is why measuring atmospheric dose is not useful.
In this video, radiation level is not measured but I think it is important to see how soil and dust are blown up by the wind.
↓ The soil blown from farms to the city area.

黒い物質が発見された南相馬市では、西からの強い季節風によって田畑の乾燥した土が舞い上げられ、市街地に吹き込んでいます。
中学校の校庭でも同様の巻き上げが見られ、黒い物質を吸い込むことによる内部被曝が懸念されます。これらの巻き上げは深刻な内部被曝を引き起こすにもかかわらず空間線量にあまり影響を与えないため、観測が難しくなっています。
