Oceanic radiation from last year's Fukushima nuclear disaster is approaching northern Hawaii, according to the latest tracking by ASR Limited.
The coastal-management consulting company has created a map that follows the movement of radiation in seawater since the Japanese earthquake on March 11, 2011.
ASR Limited suggests radiation is crossing the Pacific Ocean.
Last April, Japanese officials claimed that they had halted the release of radioactive radiation from the crippled nuclear reactors at Fukushima.
On December 5, however, the Los Angeles Times revealed that "45 tons of highly radioactive water" had been released from the plant on the previous weekend.
Greenpeace has also reported finding highly radioactive sea life off the Japanese coast.
Meanwhile, ASR Limited has also released a map showing how far the floating island of Japanese debris has travelled since last year's earthquake.
It's expected to reach the B.C. coast in 2013.
A huge amount of debris is headed toward British Columbia.
