Quote:Radiation levels 18 times higher than previously reported have been found near a water storage tank at the Fukushima Daiichi nuclear power plant, prompting fresh concern over safety at the wrecked facility.
The plant's operator, Tokyo Electric Power (Tepco), said radiation near the bottom of the tank measured 1,800 millisieverts an hour – high enough to kill an exposed person in four hours.
Tepco said water levels inside the tank had not changed, indicating there had not been a leak. But the firm said it had yet to discover the cause of the radiation spike.
I'm going to look at that ... oooooh.
The answer isn't complementary to TEPCO.
The Tokyo Electric Power Company (Tepco) had originally said the radiation emitted by the leaking water was around 100 millisieverts an hour.
However, the company said the equipment used to make that recording could only read measurements of up to 100 millisieverts.
The new recording, using a more sensitive device, showed a level of 1,800 millisieverts an hour.
The good news is nothing has changed. The bad news is they don't know how bad past worker exposures really were.
The old meters only went up to 100 mS/h (probably the maximum dose the workers were permitted). So any place where the meters pegged - was listed as 100 mS/h.
The new meters can make higher readings - and the readings are higher...
