Firefighters responded to a possible radiation leak aboard a ship at the port of Halifax on Thursday night, but later determined there was no leak of radioactive material.
The Halifax regional fire department says there were no injuries and no one was contaminated at the Ceres terminal in Fairview Cove in the city's north end.
A city news release says firefighters received a call shortly before 10 p.m. after four steel cylinders fell about six metres from inside a container at the terminal, landing in a contained area of the ship.
It says the cylinders contained uranium hexafluoride, which is the chemical compound used in the gas centrifuge process to enrich uranium that is then used as reactor fuel or to arm nuclear missiles.
Initially, division commander Corey Beals said the department thought it was dealing with ``some sort of radiological leak'' but he couldn't provide any further details.
About 90 minutes later, the department said there wasn't a leak.
