Current radiation levels in Japan and travel advice


Radioactive material from the damaged Fukushima Daiichi plant is gradually spreading outside Japan into the global atmosphere but at extremely low concentrations that do not present health or transportation safety hazards, according to the United Nations organizations closely monitoring the situation.


Japanese authorities confirm that all airports in the country, with the exception of Sendai which was affected by the tsunami of 11 March, continue to operate normally for both international and domestic operations. Continuous monitoring around these airports confirms that radiation levels are well within safe limits from a health perspective.
