Mr.Hayano explains about the CatEar is kind of noisy(when it moves) and uncontrolabe.It only moves with brainwave.

Twitter is interactive.that's a good point. We gradually get data about outside radioactive data. But not many internal exposure data.Food!

Mr.Hayano proposed Whole lunch radioactive test for school. Governer first didn't want to do the test, afraid if they find radioactivity

15/07/2012 12:17:08 WIB
hiroki @hirokiharoki

First, the test was on Yokosuka.Mr.Hayano proposed with using his own pocket money. gradually, whole lunch test spread to many areas.

There are StandingType WBC,and ChairType WBC with/without shilelds.Food Bq Checker and WBC is basically, same system. Get spectrum and peaks

15/07/2012 12:27:23 WIB
hiroki @hirokiharoki

Cpm to Bq, then Sv they calculate and create data. I131's half life 8days.So they can't say about I131 by checking WBC now.

They say Radon radioactive gus makes cancer 20000 die in US. K40 is in all people. When Mom hug baby, baby exposes K40.

Showed fig. Of 300BqInternalExposure checked by WBC. It was a very slite difference. WBC result changes. Radioactive is randam somewhat.

15/07/2012 12:39:39 WIB
hiroki @hirokiharoki

WBC is for adult size, not for child.Have 15% error. Kids need to place with stand.Because checking main point differs with kid's hight.

15/07/2012 12:42:41 WIB
hiroki @hirokiharoki

Less than 20kg kids is impossible currently with WBC FOR 2MIN. And many WBC in Fukushima need calibration.

15/07/2012 12:44:50 WIB
hiroki @hirokiharoki

10Bq per day, for a year.How much in WBC? Not all are acumulated. It gets gradually out, too, with pee/poo. Kids faster dicrease.WBC -Adults

15/07/2012 12:47:44 WIB
hiroki @hirokiharoki

...can check better.We discovered, they don't eat much cesium as we had expected(afraid). Compared with Chernobly / Minamisouma. But don't

15/07/2012 12:50:46 WIB
hiroki @hirokiharoki

Get guard down. We found 10000Bq/kg wild boar,too. Showed WBC data. Before Feburary, they didn' changed clothes.That makes higher results.

15/07/2012 12:53:11 WIB
hiroki @hirokiharoki

Need to do WBC second test for increasing or dicreasing.Ppl who eat 20Bq, and 30Bq each day increases. 1mSv/year:equals 50,000Bq/year

15/07/2012 12:56:54 WIB
hiroki @hirokiharoki

If one eat 100Bq/kg rice for a year equals 6000Bq only.It's 1digit lower than 50,000Bq. Current high risk foods are,HouseVeggy with no check

15/07/2012 12:59:07 WIB
hiroki @hirokiharoki

And main food with contaminated for some degree.There are 50Bq/kg rice.It exist. 1960era, we Japanese all eat 4Bq/day everyday.

15/07/2012 13:01:19 WIB
hiroki @hirokiharoki

1964, 550Bq/body adults. Data is accurate.Matches with caluculation with 4Bq/everyday. WBC data with no chothes change was high.Clothes were

15/07/2012 13:03:35 WIB
hiroki @hirokiharoki

Contaminated.Recommend,not only kids, parents, adults should check,too.Better result we can find.300Bq/body is minimum checkable value.
