Radiation level spiked in reactor3. Tepco “The gauge is broken”

 
One of 4 monitoring gauges in suppression chamber indicated spiking up radiation level in reactor3, which was 47.01 Sv/h at 17:00 6/21/2012.
Other gauges didn’t show any change in radiation level. The furthest one is located at 40m away from the issued indicator.
Tepco states the monitoring gauge was broken because of the humidity, but no fault is found in transmission.

It used to indicate about 0.1 Sv/h. It picked up to 17.59 Sv/h at 5:00AM 6/21/2012.

3号機検出器が故障か=放射線量が急上昇-福島原発
東京電力は21日、福島第1原発3号機の原子炉格納容器下部にある圧力抑制室で、放射線量を測定する検出器の一つで数値が急激に上昇し、毎時約4万7000ミリシーベルトを記録したと発表した。他の検出器はほとんど変化がなく、同社は「検出器の不具合と考えられる」としている。(2012/06/21-20:37)
