– Tepco testing tainted earth at No. 1 plant (Japan Times, Aug 23, 2013):
Utility begins digging ground to assess extent of contamination
FUKUSHIMA – Tokyo Electric Power Co. on Friday started digging up soil tainted with highly radioactive water discharged from a storage tank at its Fukushima No. 1 nuclear plant to test its radiation levels.
The utility will dig areas measuring 12 sq. meters in total to a depth of 40 to 50 cm where pools of leaked radioactive water formed, and then measure levels to determine how far the contamination has spread and how much soil needs to be removed.
