Setagaya, Tokyo's High Radiation Supermarket: It's Radium Again, Emitting 40 Millisieverts/Hr Radiation

According to the Ministry of Education and Science, a glass bottle was found 40 centimeters below the surface, which was emitting 40 millisievert/hour radiation. Radium-226 is suspected.

(How many more radium-226 bottles are there buried in Setagaya-ku?)

From Yomiuri Shinbun (11/1/2011):


Regarding the high radiation detected inside the supermarket compound and in the vicinity in Hachimanyama in Setagaya-ku, Tokyo, the Ministry of Education and Science announced on November 1 that the cause of the high radiation was likely to be "radium-226" buried in the soil.


At 40 centimeters below the ground surface, 40 millisieverts (or 40,000 microsievert) per hour radiation was measured, according to the Ministry. 40 millisievert is 40 times the annual radiation exposure limit [still 1 millisievert, though it is likely to change very soon] for the general public [not engaged in radiation work].


According to the Ministry of Education, there was a glass bottle at 40 centimeter below the surface, and the radiation on the spot was 40 millisieverts/hour. The radiation on the ground surface there was 1 millisievert/hour. The work is proceeding very cautiously because the radiation level is extremely high. The bottle will be removed on November 2 or after.

The Ministry and the Setagaya government have been saying "There is no effect on health". Really. (1 millisievert/hour, 24 hours a day, 365 days a year, and we would be talking the radiation exposure in sievert.)

yeah right radium, I guess it wasnt planted there then? a bit of social engineering going on here by our friends in the government , "Radiation is all around us and we are still fine " goes the chant... this is becoming more like 9/11 everyday.. lie and pull the wool over everyones eyes.

Why not find buried bottles of radium? I'm sure there are all sorts of treasures buried all over the place as proper waste disposal is expensive and also in the "good old days" it wasn't given so much consideration. Now with people out and about with their own meters more and more dangerous stashes are likely to be uncovered. Don't take this as an apology for the terrible old men who want to lie and cover up and play games with the truth - but in this and the other case I can believe that it actually was local contamination from something buried a long time ago.

Anyway how the F is it possible to say 40 millisieverts per hour is 40 times the annual exposure limit of 1 millisievert per year? It aint. Its 350,000 times the annual exposure limit. (40 x 24 x 365 / 1).

How long this radium have been buried there ? By who ? That would be useful to know in order to find the location of the potential other buried radioactive materials.
