So the question is: Since radiation has been found in food, how dangerous is that to us? Is it safe?
放射性ストロンチウムを検出=原発30キロ外、福島6市町村―文科省
同省は3月16~17日、第1原発の30キロ圏からやや外にある福島県浪江町の2カ所と飯舘村の1カ所で採取した土壌を分析。1キロ当たりストロンチウム89が最大260ベクレル、同90が最大32ベクレルだった。
大玉村、本宮市、小野町、西郷村で19日に採取された植物も分析。1キロ当たりストロンチウム89が最大61ベクレル、同90が最大5.9ベクレルだった。サンプルの植物は食用野菜ではないという。
ストロンチウムは、カルシウムと似た性質を持ち、人体に入ると骨に沈着し、骨髄腫や造血器に障害を引き起こす恐れがある。ストロンチウム90は半減期が約29年と長く、過去の核実験の際に飛散し問題となった。同89は半減期が約50日。
Translation:
Two types of radioactive strontium have been detected in soil tests just outside of the 30 kilometer (18 mile) nuclear exclusion zone near the crippled reactors in Fukushima.
On Monday, Japan's Ministry of Education announced the results of sample surveys on soil and plants in Fukushima Prefecture, saying that Stronium-89 and Stronium-90 have been detected in the samples taken.
Samples were taken for analysis between March 16th to 17th. One set of samples were collected from Iidate in Namie-Cho in Fukushima Prefecture, just outside of the 30-kilometer exclusion zone. Those samples showed Strontium-89 up to 260 becquerels per kilogram, and Stronium-90 was detected at 32 becquerels.
Samples of 19 plants were also taken from Ootama village, Ono-machi, and Saigo village. In those samples, Strontium-89 was detected up to 61 becquerels per kilogram, and Strontium-90 was detected up to 5.9 becquerels.
Strontium has properties similar to human bone tissue and when deposited into the body in large amounts, can cause myeloma and hematopoietic failure. Strontium-90 has a long half-life of about 29 years, which was discovered during nuclear testing and Strontium-89 has a half-life of about 50 days.
Extra information:
The considered safe level for radiation is 300 becquerels per kilogram. For a comparison, see this chart:

Becquerels—a measure that represents one radioactive event per second—per kilogram.
- Reality - Becquerel (Bq)
- The unit of measurement for radioactivity. An activity of one Bq means that one decay takes place per second. [Nothing to do with kg.]
From this recent news and Fukushima being raised to a level seven disaster, I've been getting lots of mail from the Peanut Gallery that claims this new information justifies the gaijin panic and flight out of Japan. Sorry, I couldn't disagree more.
A deeper examination shows, if anything, this new evidence proves you panicked and ran away - without any rational reason to do so at all - if, upon examination of this new information, that you decide to stay here anyway.
For you foreigners and Tokyoite Japanese who ran away - and are still outside of Japan - then, please, stay there. Stay away. Don't come back to Japan. Fukushima is now a level seven. The food is radioactive. It's too dangerous! We're doomed!
Oh, and if you want to eat healthy... Stop the fast food.
I am not surprised that the level was raised. I had expected that not long after the explosions. It is at the level I said it was going to be. Wasn't a guess, just used commons sense, logic and facts.
ReplyDeleteIt took a long time to finally change the level. The reactors were already melting a few weeks after the quake. Surprising is that it is still not over or even in control.
Also they are radiating the oceans, which will take at least 25 years to recover from. That is a big deal for all the countries that fish the Pacific and use its water.
"The considered safe level for radiation is 300 becquerels per kilogram. For a comparison, see this chart: "
ReplyDeleteThe chart you link to is fine, but note becquerels and Sieverts can't be compared. 1 becquerels releases a different amount of radioactivity depending on the element it is released from.
So 1 becquerel from a plutonium source is much more serious than from iodine.
The stuff you link to about coal is a page with a massive number of links. I mean ... black lung? Does that still exist today? Are current workers in Japan that burn coal exposed to this?
Is this exposure necessary and not avoidable in someway?
Ultimately what I want is for the free market to decide these things. Is that so bad?
I can assure you nuclear power is not ready for prime time, it would not survive on in the market place. It might at some point in the future, but right now no insurance company would dare insure them.
