"Becquerels" and Japan's changing "safety" standards for radioactive contamination in food and water

In this video I explain the unit called a "becquerel" which is used to measuring radioactive contamination in water, food, and other things. I also discuss the Japanese government's "safety" limits.
Having lived in Japan for several years and speaking to non-native English speakers so much, I really noticed in this video how slowly I've come to speak. I apologize and will try to return to "native" speed for future videos.
Japanese Science Ministry (MEXT) radioactive contamination in tap water information:
I have not had time to thoroughly investigate it, so I didn't report on it, however, going through the .pdf archives of radioactive iodine and cesium in tapster I was unable to find any reference of 210 becquerels/liter which was a high that the Tokyo tapster hit as reported by many local and foreign news sources when it happened. Here is one of many mainstream western media references to it (http://www.msnbc.msn.com/id/42225380/ns/world_news-asia_pacific/t/radiation-fea­rs-spread-tokyo-drinking-water/)
Japanese Health, Labor, and Welfare Ministry March 17, 2011 document detailing new safety limits of radioactive contamination in food and water:
WHO, Germany, and U.S. radioactive iodine and cesium permitted levels information source:
(This site has some good information, and some information that I would prefer to verify with a second source. If I were making a presentation beyond the scope of this informative video, I would seek an additional source to verify these figures, however time has not permitted me to do so right now.)

And it is likely that it will do so.

Do not believe for a moment it is only within Fukushima Prefecture, because it isn't. Prefectures and municipalities that have found radioactive cesium in the ashes in the household garbage incinerators have already adopted the Fukushima standard as their standard, due to the lack of specific guidance from the government addressed to their specific localities.

The Ministry of the Environment has already issued a guidance to mix the potentially radioactive debris with regular industrial waste and burn, so that the resulting ashes will test lower than 8,000 becquerels/kg cesium content. Now the limit will be 100,000 becquerels/kg; coupled with the mix and match operation, probably they can bury just about anything. Maybe even those radioactive debris and waste on Fukushima I Nuke Plant.

According to the Guardian article on July 13, the workers at Fukushima I Nuke Plant are still removing 23,000 firefighter suits discarded around the reactors, packing them up, and shipping to a nuclear waste disposal facility. Why bother?

Spread radiation with impunity!

From Jiji Tsushin (7/14/2011):

Limit for burying radioactive debris from Fukushima to be raised to 100,000 Becquerels/Kg - Ministry of the Environment


Japan's Ministry of the Environment started the discussion on July 14 to raise the limit for radioactive cesium in the ashes from debris in Fukushima that are suspected to be radioactive in the wake of the Fukushima I Nuclear Plant accident. The current safety limit is 8,000 becquerels/kg of radioactive cesium. The Ministry is considering to raise this limit to 100,000 becquerels/kg. The Ministry will call a meeting of experts to come up with the conditions for burying the ashes safely, such as measures to prevent groundwater contamination.


Last month, the Ministry announced its policy to allow the burying of the ashes as long as they test 8,000 becquerels/kg and lower, and to temporarily store the ashes if they exceed that level. However, with discoveries of ashes from regular household wastes that exceed 8,000 becquerels/kg in Tokyo and Chiba, the Ministry has decided to speed up on the policy on the disposal after the temporary storage.

You can be assured that these experts would never object as a group. Probably there are one or two who will raise a token concern (that's their role), but the majority will give them assurance that it will be OK, and the Ministry will quote this expert group as the reason for its decision.

I will look up information on the final waste disposal plant specs in Japan.

I can almost bet there are no rubber liners or anything to prevent any leakage of toxic substance, not to mention radioactive waste that should be going to nuclear waste disposal facilities to begin with. Why do I think that way? Because if the so-called experts are thinking about putting in measures to prevent groundwater contamination, there is none, as of now.

[Note du Curateur] Au Japon aussi on prépare le feu d'artifice le 14 juillet...
Bref, on casse le thermomètre et on autorise tout le monde à cacher les poussières radioactives sous le tapis (et on ferme sa gueule...)
