#Radioactive Car Emitting Over 30 Microsieverts/Hr in Musashino City in Tokyo Was Returned to Fukushima

The owner of the car got it from his friend in July and the car was from (guess where) the 20-kilometer radius "no entry zone" in Fukushima Prefecture.

The 20-kilometer "no-entry zone" was officially off-limit until June and the residents weren't allowed to use their own cars until September. Unofficially, there were "rumors" (i.e. not reported in the media) during the summer that people were hired to go and retrieve vehicles inside the 20-kilometer zone. There were also "rumors" of sudden deaths among people who were doing exactly that. The existence of this car in Musashino City, Tokyo is a proof that these reports may have been true.

The car was found emitting over 30 microsieverts/hour radiation at the front grill and inside the engine room. At the perimeter of the parking lot at 1 meter high, the air radiation was 3 microsieverts/hour. Judging by the way the city crafted the announcement, their survey meter went overscale at 30 microsieverts/hour, and the actual radiation level could be much higher.

It was only on December 21 that a citizen finally alerted the city about this radioactivity on wheels.

From the announcement at the Musashino City website:

中町2丁目の駐車場にあった乗用車について、12月21日(水)に市民から高放射線量の情報提供を受け、市で測定したところ、高放射線量が確認されたため、下記のとおり対応いたしました。

Regarding the automobile in a parking garage in Nakacho 2-chome, we were notified by a resident on December 21 of the high radioactivity. We measured the radiation level and confirmed it to be high. Therefore we did the following in response:

 市は、現地で数値の確認を行い、安全を確保したうえで、武蔵野警察の協力を得て、立ち入り禁止措置を行いました。

We confirmed the radiation, and with the help of the Musashino City Police closed off the area after securing safety.

 その後、都ならびに国の指示をあおぎ、対応が決定するまでの間、車を市役所地下駐車場に移し、周辺の出入りを制限して保管しました。

Then we asked for guidance from the Tokyo Metropolitan government and the national government. While we waited for the answer we moved the car to the underground parking at the City Hall, and kept it there limiting the access.

 市は、内閣府原子力災害対策本部に除染の支援を要請し、車の放射線量が毎時30マイクロシーベルトを超えているため、福島県の警戒区域内に戻すことが適当であると決定いたしました。

We asked for assistance in decontamination from the Nuclear Disaster Response Headquarters of the Prime Minister's Office. Since the radiation from the car exceeded 30 microsieverts/hour, it was decided that it would be appropriate to return the car inside the "no entry zone" in Fukushima Prefecture.

 22日(木)午前に、内閣府と東京電力において、車を福島県に搬送し、除染と放射線量の再測定を実施します。線量が一定の基準を下回らなければ、警戒区域から持ち出し不可となります。

On December 22 morning, the Prime Minister's Office and TEPCO would transport the car to Fukushima Prefecture, and conduct decontamination and radiation measurement. If the radiation would not drop below a certain level, the car would not be able to leave the "no entry zone".

 車の所有者である市内の男性は「7月に知人から譲り受けた」としており、福島第一原発事故前後に警戒区域内で使われていたものであったことが判明しました。

The owner of the car is a city resident who says he received the car from his acquaintance in July. It has been revealed that the car was used inside the "no-entry zone" before and after the Fukushima I Nuclear Power Plant accident.

 車を移動させた後の、近隣区域の放射線量は、市の基準値(毎時0.23マイクロシーベルト)を下回っていることを確認いたしました。

After the car was moved, the radiation levels in the vicinity were confirmed to be below the limit that the city sets (0.23 microsievert/hour).

Radiation levels (from the chart at Musashino City's website, above):

  • Perimeter of the parking lot at 5 centimeters off the ground: 2.60 microsieverts/hour

  • Perimeter of the parking lot at 1 meter off the ground: 3.08 microsieverts/hour

  • Car, front grill: more than 30 microsieverts/hour

  • Car, inside the engine room: more than 30 microsieverts/hour

  • 7 meters from the car in both north and south directions at 1 meter off the ground: 0.19 to 0.23 microsievert/hour

After the car was removed, the radiation levels on the parking lot dropped to 0.11 microsievert/hour, post-Fukushima normal, so to speak.

It looks like there is a kindergarten within 3 minutes of walk from this particular parking lot, which costs about US$320 a month to rent a parking space. This car has been in this parking lot, and running around in town and maybe beyond, for 6 months. It would have continued to do so without the report from a citizen armed with his/her survey meter.

How convenient that the meters have an upper limit and people always "forget" to check again with a properly ranged meter.

And, how very convenient that they apparently don't check the passenger cabin and the car underside. As their surfaces readily attract and hold radioactive stuff, it apparently is considered "polite" not to look there.

So we are made to believe that this car had 30 microsievert, just because this was the upper measurement limit of the meter used.
Even if the car actually might be nearer to 30 millisievert instead of 30 microsievert.

And we believe that this "10-sievert-hot spot" at the offgas tubing at Fuku-I has actually 10 sieverts, and nobody seems to be interested to re-check with an appropriate meter. The findings could be too disturbing for our feelings, so better look away.

The Russians abandoned thousands of vehicles from cars to helicopters because of contamination.
They implemented controls, and every car that exceeded the limits was seized immediately, even if it was a nomenclatura moskvitch.

I haven't yet heard of a single such case in Japan. They appear just to put the cars back to Fukushima prefecture, where allegedly nobody cares about such "little radiation" nowadays.

Waste not, want not. Recycle your "little radiation".

Did anyone make note of where we lost our minds?

Good friend!
Some people just don't get radiation. You can't see it, can't smell it, heck most times you don't feel it.

Great, that's where I live. Distressing news.

Buying used cars is hobby for someone and for others it might be a business, if you are interested in buying innovative used cars for your business you should try Japanese auctions.
