Aide to Japan PM quits over radiation limits

"Al Jazeera's correspondent, Divya Gopalan, reporting from Tokyo, said the expert criticised the government’s handling of the crisis and said their action was knee-jerk.

Kosako said he could not stay on and allow the government to set what he said were improper radiation limits for elementary schools near the crippled plant.

Our correspondent said: 'The expert was particularly critical of the government’s nuclear radiation exposure limit. His biggest attack was the government limit for children, which he said was 20 times too high in Fukushima Prefecture.

'He said the radiation limit for children should have been much lower as they are being exposed to radiation, and that his recommendations were ignored.' " Al Jazeera
