日本の放射能の懸念に関して、特に日本のメディアで使用されているマイクロシーバーツについて、いくつかはっきりさせておきたい。
我々が通常の放射能を浴びる量は一時間に0.27μSvとなっており、言い換えれば年間2400μSvを浴びていることになる。原子力発電所によるウラン、セシウム、プルトニウム等の放射能も考慮しなければいけないから、一時間に0.11 μSvを更に考慮する必要がある。合計で0.38μSvの計算となる。一時間に100.000μSvが放射能により支障をきたす最初のサインとみなされている。
我々は不定期に事実の記事を今後も日本の様々な地域に
配信して*いきます。危険なものそうでないもの含めてです。場所日時含んだ本当の記事をお届けします。
With recent concerns about increasing radiation in Japan, all sorts of readings with comments have been published. We would like to clarify a few things when hearing of microsieverts (μSv), particular used in Japanese media.
Here, the natural background radiation is approximately 0.27 μSv per hour. In other words, every one of us receives a dose of 2400 μSv per year, without being additionally affected by any artificial radiation. Additional radiation as exposed trough escaping Uranium, Cesium or Plutonium by nuclear power plants needs to be taken into account. What we consider still normal is an increase by 0.11 μSv per hour through one of these sources. Therefore, a total of 0.38 μSv per hour is still normal. Readings of 100.000 μSv per hour are known to cause first signs and symptoms of radiation related injuries.
On
Twitter*, we post actual readings of various regions in Japan on an irregular base. This is meant to satisfy alarming, as well as non-alarming news. Simply the real reading with place, date and time for your information. Our
RD1503 is made by Quarta Rad Ltd. in Russia and is distributed through
Sato Shouji Inc. in Japan. Calibration has been completed and all readings are in μSv/h. Please judge for yourself.
