Undated photo of the Hyundai Oakland
The Hyundai Oakland from Shanghai arrived early Tuesday morning in Tacoma. Overnight, the ship was moved up to the Port of Seattle to continue offloading its cargo.
The Coast Guard boarded the ship on Tuesday as a routine security measure, and found increased levels of radiation in the engine’s air filter.
The Department of Health then inspected the ship. The air filter was changed and the ship was able to continue on.
