Fukushima school requires parents to sign on a letter of acceptance to have students clean the pool

A junior high school in Fukushima prefecture sent a letter of acceptance to the parents.

They are going to have swimming class this year. The school is going to have the students clean the pool.

The letter reads,

The school is going to have swimming class from this July.

They are going to hold a general sports meeting of the junior high school union from 6/4 to 6/5/2013.

During the meeting, the school is going to clean the pool with teachers, staff, students who don’t attend the meeting and also couldn’t advance to the next round of second day.

We are to ask if you allow your children to clean the pool or not. Please write yes or no and submit it to the class teacher by 5/24/2013.

Last year, the radiation level of the pool water after the class was lower than 10Bq (Unit unknown). It is confirmed that there is no problem to clean the pool.


Please bring Tshirt, shorts, towel, scrubbing brush, sandals, rubber gloves (if you want).

Une école de Fukushima exige que les parents signent une décharge pour que les enfants nettoient la piscine scolaire


Un lycée de la préfecture de Fukushima a envoyé une décharge à signer aux parents.
Ils vont reprendre les cours de natation cette année. Le lycée va demander aux élèves de nettoyer la piscine.

La décharge dit :

Le lycée va reprendre les cours de natation en juillet prochain.
Un rassemblement général et sportif de l’Union des premiers cycles du secondaire se tiendra du 4 avril au 6 juin 2013.
Le lycée va procéder au nettoyage de la piscine pendant ce rassemblement avec les enseignants, le personnel, les élèves qui n’y participent pas et également ceux qui seront éliminés dès la seconde manche du deuxième jour.
Nous vous demandons de nous préciser si vous permettez ou non à vos enfants de nettoyer la piscine. Merci de répondre oui ou non et de remettre ceci à l’enseignant de sa classe pour le 24 mai 2013.
L’an dernier après les cours, la radioactivité de l’eau de la piscine était inférieur à 10 Bq (unité non précisée). Il est confirmé qu’il n’y a pas de problème pour nettoyer la piscine.

Merci de fournir les T-shirts, shorts, serviettes, brosses à récurer, sandales, gants en caoutchouc (si vous le désirez).

  1. Oh, but they need those innocent souls to scrub that dirty radioactive mud! Last year scientists issued this practical summary of the process:

    “About 90% of the radioactive Cs in the sediment mud of a school’s swimming pool in Fukushima, Japan was removed by treatment for 3 d using the alginate immobilized photosynthetic bacterium Rhodobcater sphaeroides SSI. Even though batch treatment was carried out 3 times repeatedly, the activity of immobilized cells in removing Cs was maintained at levels of about 84% (second batch) and 78% (third batch). Cs was strongly attached to the sediment mud because, even with HNO(3) treatment at pH of 2.00-1.60 for 24 h, it was not eluted into the water. Furthermore, more than 75% of the Cs could be removed without solubilization with HNO(3). This suggests that the Cs attached to the sediment mud was transformed into immobilized cells via the Cs(+) ion by the negative charge of the immobilized cell surface and/or the potassium transport system of the photosynthetic bacterium.”

    SP: Look at the great learning opportunities! (Sarcasm on) They will learn how to scrub away some of the most dangerous gamma ray byproducts of a nuclear meltdown and possibly even get a few plutonium specks at the same time. And with no full body suits or respirators! What a wonderful bunch of school administrators to allow such a grown-up real world experience! (Sarcasm now OFF!)

    Would I let my own child even attend such a school? Not in a million years…we would have moved to Okinawa even if we had to clean restrooms for a living. There we would have a chance at a near normal lifespan. At least until they blow another nuclear plant in Japan (and they seem poised to restart a few more of these nation killers).

    Sayonara Japan!

  2. Parent needs to have a “letter’ from the school CERTIFING the radiation testing and SAFE levels in the pool, full and empty. Cause its not just the concrete of the pool. Fill it with groundwater..guess what. So a certified letter from the school which provides the testing data and radiation levels as of the DAY OF CLEANING. And a letter saying the pool is safe, and will always be under XXXXX amount of radiation. The school also needs to certify radiation levels daily with a WORKING dosimeter. Guess that would make the school tell the kid to stay home..

  3. Is it just me, or does Chlorine actually assist in keeping Alkali Metals such as Cesium and Strontium (et al) dissolved?

    Also, are students in attendance year-round in Japan, or does this refer to a “summer-school” where such students are lowly-regarded?
    I am not familiar with the differences or similarities with school systems between Canada and Japan.

    Smile. 🙂 It confounds biometrics!

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.
