Several emergency crews are on the scene including a HAZMAT team.
The leak began when a container being loaded onto the deck of the Atlantic Companion dropped. The incident happened around 10 p.m. Thursday.
The fire department went to test for radioactivity at the Ceres terminal. The first team found nothing, but a second test picked up higher than normal levels of radioactivity.
The Atlantic Companion is a Swedish-built ship owned by Atlantic Container Line ACL.
