WHO spokesman Gregory Hartl said Friday the organization "is not advising travel restrictions to Japan" outside the 30-kilometer (18.6-mile) exclusion zone around the Fukushima Dai-ichi nuclear complex.
Hartl said that includes Tokyo where "radiation levels have increased very slightly, but are still well below the absolute levels of radiation where it would be considered a public health risk."
Hartl said "at this moment the public health risk beyond the 30-kilometer radius ... is small."
He also said that "in general travelers returning from Japan do not represent a health hazard."
