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.
