Radiation levels are within the norm in Russia's Far East region of Sakhalin as of early Tuesday morning, a spokesman for the regional emergencies ministry said.
"There are no deviations from the norm in all districts of the region," he said adding that all radiation monitoring services continue working intensively.
Tokyo Electric Power Company, or TEPCO, the operator of the troubled Fukushima Daiichi nuclear power plant, found radioactive water was seeping into the ocean from a crack in a concrete pit that contains power cables near the Number 2 reactor's water intake. The level of radiation on the surface of the pit's water was measured at over 1,000 milisieverts per hour.
Japan's nuclear watchdog said the crack could be the source of recent seawater contamination.
The death toll from the March 11 quake and tsunami has exceeded 12,340, while nearly 15,350 remain unaccounted for.
