220 Bq of cesium from daily food in Fukushima

Contamination of daily food by cesium all over Japan

Mainichi newspaper and Tokyo Metropolitan University measured daily food of 11 people living in 11 different locations.

The samples were taken from 11/13 ~ 11/15. They mixed 3 meals and snacks and then put them into a mixer and measured cesium by germanium semiconductor detector taking 2 hours.

The result shows in the worst case, you take 220 Bq of cesium from breakfast, lunch, dinner and snacks everyday non-stop.


Dateshi Fukushima 140 ~ 220 Bq per day

Takasakishi Gunma 30 ~ 81 Bq per day

Shiraishishi Miyagi 29 ~ 33 Bq per day



Below is a famous graph of ICRP. It shows how much radiation is stocked in your body if you keep having contaminated food everyday.

Effects of contaminated food on the body

Abscissa axis = date

Vertical axis = Bq

The simplest put is, if you have 10 Bq from food everyday ,you become as contaminated as the 10 Bq food in 2 months. (If you weigh 50kg)

  1. and this is only basic food. Add contaminated water, contaminated tea or beer, contaminated air, and must add heavilly contaminated plutonium fish a few times.
    Then all the air contamination must also be added, becaused cesium gets into the lungs from so many different sources such as air filter, dusts or by the winds from Fukushima or from forest, etc…(as well as plutonium, americinium, technotium, kadnium, etc….).
    Plus add all the external contamination sources (car, mobile phone, soil, building walls, …).
    Radiation effects on a population are increasing over time and generations. This means that children of peoples who have received more than about 50 bq of internal contamination, will be in worst shape than their parents. And those living in contaminated enviromnet but with not affected parents, will develop diseases. That’s what it is. Can you beleive the Japanese governement is doing this to its entire population? Without proper actions, things are not going to get better. Rare are the healthy and normal children in belarus and only 20% of children normal healthy in Kiev. And things are not getting better there. We are talking of a lot of people, at least Kanto and anywhere north-East of Osaka. Sorry to brake the party, but it is time the Japanese people start to take care of themself because the pronostics are worstening every day normal popuplation safety is not implemented.

  2. Fishes are getting contaminated, especially with cesium. 90% of the cesium is trapped in muddy particles which gets absorbed by seaweed and works its way up the food chain. Cesium is a muscle seeker and Strontium is a bone seeker. We’re seeing cesium in the fish meat and strontium in the fish bone.

    I just stumbled upon this study detailing high altitude radioactive contamination from Fukushima. It uses TEPCO and MEXT emission data to develop dispersion models of the radiation. If the models are correct the concentrations of contamination at upper altitudes are orders of magnitude higher than the concentrations at near ground levels.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
