Radioactive release from Fukushima plant rises

The operator of the crippled Fukushima Daiichi nuclear plant says the amount of radioactive substances being released from the plant has risen slightly. It attributes the rise to increased human activities onsite.

Tokyo Electric has been measuring the levels of radioactive substances released from damaged reactors at the plant since the accident in March.

The level measured onsite was 800-trillion becquerels per hour immediately after the accident.

Readings continued to decline, and in November and December dropped to 60 million becquerels per hour. That is about one 13 millionth the initial level.

But the company says the levels were slightly up to 70 million becquerels per hour in January.

The company says that radioactive materials around the No. 2 reactor, the surrounding of which is still highly contaminated, were stirred up by a number of workers going in and out of the building.

They were working to insert an optical fiberscope into the containment vessel as an initial step toward decommissioning the reactor.
