The Sellafield nuclear site is being operated at "reduced manning levels" following "the detection of elevated levels of radioactivity".
Operator Sellafield Ltd said in a statement:
As a result of a conservative and prudent decision, the Sellafield site is operating normally but with reduced manning levels today. This follows the detection of elevated levels of radioactivity at one of the on-site radiation monitors at the north end of the site. Levels of radioactivity detected are 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. The site is at normal status and employees and operational plants are continuing to operate as investigations continue."
