[ RadSafe ] Concerned About Lack of Good Information

[Jeff Terry]

There are apparently mistakes being made in calculating/measuring dose rates:

No updates were released on Saturday and only a small NEI update today:

UPDATE AS OF 9:30 A.M. EDT, MARCH 27:
Tokyo Electric Power Co. workers on Sunday were using pumps to remove highly contaminated water from the basement of the turbine building of reactors 1 and 2 at the Fukushima Daiichi nuclear power plant.

TEPCO also was preparing to remove water from the turbine building of reactor 3. Removal of the contaminated water is necessary to continue power restoration to the plant.

By Sunday, water injection to the pressure vessels at reactors 1, 2 and 3 had been switched from seawater to freshwater. 

Off-site power has been restored to all units and work to connect equipment is ongoing. Progress is being slowed by high radiation levels and wet equipment.

TEPCO said that earlier reports of extremely high radiation levels measured in the water in the basement of the reactor 2 turbine building were inaccurate, according to news reports.


UPDATE AS OF 6 P.M. EDT, MARCH 26
At this time, sources such as the International Atomic Energy Agency,Tokyo Electric Power Co. and the Nuclear and Industrial Safety Agencyhave reported no new developments at the Fukushima Daiichi nuclear power plant. NEI will report on any new developments on this website on Sunday morning.

The radiation levels are decreasing at the KEK facility (Tsukuba):

which are now at 0.17 uSv/hour. 

They have not indicated an increase in short lived isotopes since March 20.
