The government should consider evacuating children and pregnant women from a wider area around the Fukushima No. 1 power plant because radiation levels remain high even outside the 20-km no-go zone, Kumi Naidoo, executive director of Greenpeace International, said Thursday in Tokyo.

Naidoo's team of radiology experts found hot spots that had a maximum hourly reading of 45 microsieverts of radiation alongside a school zone.

While the area likely had high levels of radiation as a result of the landscape or other natural conditions, Naidoo insisted the central government should conduct thorough checks and provide accurate and fast information to local residents.
