UK's Sellafield says detects elevated levels of radioactivity
"As a result of a conservative and prudent decision, the Sellafield site is operating normally but with reduced manning levels today," it said in a statement.
The site said only essential workers were being asked to report to work. It said the levels of radioactivity detected were above naturally occurring radiation, but well below that which would call for any actions to be taken by the workforce on or off the site.
