Health warning labels on mobiles!

The law requires that mobile stores to display the Specific Absorption Rate (SAR) levels — that is the amount of radio-frequency energy absorbed by the body per unit of body mass — of every phone either on the handset itself or on a poster within the store.

The legislation was passed despite opposition from mobile phone industry representatives,who argued the measure could be seen as supporting the view that higher emissions might be linked to health risks.

According to US Federal Communications Commission rules,cell phones cannot have a SAR greater than 1.6 watts per kilogramme.

San Francisco mayor Gavin Newsom is to sign the ruling into law after a 10-day public comment period.
