Tokyo park closed after rocketing radiation levels found

Tokyo's Toshima ward office workers talk with a guard at a park, where high radiation has been detected on a playground equipment (rear), in Tokyo, Japan, 24 April 2015.

Soil underneath a slide at the park in the northwest of the Japanese capital showed radiation readings of up to 480 microsieverts per hour, the local administrative office said.

Anyone directly exposed to this level would absorb in two hours the maximum dose of radiation Japan recommends in a year.
