nuclear waste

Now, UK government scientists have been fighting back, with an unusual arsenal including sniffer dogs, drones and nuclear waste models.

Investigators say the contamination is not related to a nuclear waste leak, and that there was no impact to "the environment, or the public".

It was found on a post nearby to where millions of gallons of liquid nuclear waste are stored, but there was no leak from the waste tanks, the report said.

Tens of thousands of workers will be needed over the next 30 to 40 years to safely remove nuclear waste, fuel rods and more than one million tons of radioactive water still being kept at the site.

Crew members plowed through ice, buzzed vessels attempting to dump nuclear waste, dodged harpoons, and spent almost a week in a Siberian prison.
