Fallout From Fukushima No. 1 On Rise

TOKYO, Japan — The amount of radioactive materials released from the Fukushima No. 1 nuclear power plant has risen this month compared with December, Tepco said.

In late January the total was 70 milllion becquerels per hour, which compares to 60 million becquerels in December 2011.

These figures are from Tokyo Electric Power Co., which attributes the increase to the displacement of radioactive materials that had settled on facilities and equipment due to work done on reactors 2 and 3.
