Fukushima local government stopped urine test to measure internal exposure

Even though urine testing has been one of the most major way of measuring internal exposure, Fukushima local government decided to abandon the way.

They have been “studying” about urine testing with the National Institute of Radiological Sciences but they reached the conclusion that it is not as accurate as WBC (whole body counting).

WBC requires a facility which costs more than 10,000,000 JPY and can test only 40 people a day.

They therefore have been trying to improve urine testing since June.

The National Institute of Radiological Sciences explained to the Fukushima local government that urine testing needs 1.6 liters of urine to get as accurate result as WBC, also it takes a “long time”.

Anyway, if you would like to have urine test this institution offers you the service.

「尿で被ばく量測定」断念=精度に課題、専用機で検査-福島
福島県は20日、国と放射線医学総合研究所が進めていた尿検査による内部被ばく量の測定について、専用検査機「ホールボディーカウンター」(WBC)に比べ精度が低いとして、実用化を断念したことを明らかにした。担当者が県議会で説明した。
WBCは1台数千万円と高額な上、検査人数も1日40人が限度。放医研は簡単にできる尿検査で被ばく量を割り出す方法を模索し、6月に始まった県内3町村の住民を対象とする先行調査で、WBCと並行して100ミリリットルの尿を採取して調べていた。
県が放医研から受けた説明によると、尿検査でWBCと同じ精度を得るには1日分の尿量(成人で約1.6リットル)が必要で、時間もかかることが分かった。県はWBCで内部被ばく検査を進める方針。(2011/12/20-21:25)
