Nature: In 2004, the European Union’s executive body, the European Commission, issued a directive to limit workers’ exposure to strong electromagnetic fields. Such fields can be hazardous at the high frequencies used in the telecom and power industries, but there’s little evidence of harm at the lower frequencies used in MRI scanners. In response to complaints from medical physicists and others, the directive was suspended in 2007. Now, reports Nature‘s Alison Abbott, the EC is proposing a new, amended version of the directive.
