Radiation levels around Japan’s Fukushima nuclear plant are 18 times higher than previously thought, Japanese authorities have warned.
The Tokyo Electric Power Company (Tepco) had originally said the radiation emitted by the leaking water was around 100 milliseverts an hour.
However, the company said the equipment used to make that recording could only read measurements of up to 100 milliseverts.
The new recording, using a more sensitive device, showed a level of 1,800 milliseverts an hour.
The new reading will have direct implications for radiation doses received by workers who spent several days trying to stop the leak last week, the BBC’s Rupert Wingfield-Hayes reports from Tokyo.
