European ports should check radiation levels on all ships coming from Japan to see if they exceed a new limit after last month’s nuclear accident, the European Union’s executive said on Friday.

“We want to exclude any risk, even if it is a very small one, for the safety of the workers in the harbors and the citizens,” EU Energy Commissioner Guenther Oettinger said in a statement.

The European Commission suggested a new EU-wide limit of 0.2 microsievert-per-hour above normal levels. The proposal was not binding and individual countries will have to decide whether to comply.
