A North Korean scholar says Pyongyang is closely monitoring whether radiation from Japan's stricken nuclear plant will reach its territory.
Yoon Yong Geun made the comments Tuesday at the start of talks with South Korean experts about an active volcano touted in the North as leader Kim Jong Il's birthplace. The talks took place at a South Korean border village.
He said the North was "monitoring diligently if radioactive contamination could reach us."
South Korean officials say traces of radioactive material believed to be from the leaking Fukushima nuclear plant have been detected across South Korea but the amounts are far below anything that would cause health problems.
