London: Nine out of 10 sunbeds expose users to unsafe levels of radiation - which could cause cancer - and most of them emit double the European limit, new research has found.
Experts warned that users were at an increased risk of cancer after tests showed that hundreds of sunbeds exceeded the 0.3 watts per square metre (Wm2) ultraviolet (UV) radiation limit, Sky News reported.
Scientists from the University of Dundee tested 402 sunbeds between October 2010 and February 2011 and found that only 10 percent complied with the safety limits.
The rest an had average UV radiation levels of around 0.6Wm2.
The Sunbed Association said that the study was "two years out of date" and all units made since the introduction of limit in April 2009 are compliant.
The British Association of Dermatologists has called for more regulation of the sunbed industry.
