Radiation from all cell phones is dangerous to human health and the devices should be used sparingly, Russia's consumer rights and human wellbeing agency said on Monday. The agency was responding to speculation that Russia would follow France's lead and ban the iPhone 12.

"Radiation from all cell phones is dangerous for humans, especially for children. It is important to follow safety rules when talking on a mobile phone: the call should not last more than two minutes, and the minimum pause between calls should be at least 15 minutes," a spokesman for Rospotrebnadzor said, according to Russia's Gazeta news site.

The spokesman added that cell phones should be placed aside while the user is sleeping, and should ideally be carried in bags rather than pockets.

Earlier this month, France's National Frequency Agency (ANFR) demanded that Apple withdraw the iPhone 12 from sale in the country after it found that the device emits more electromagnetic radiation than European Union regulations allow.

The ANFR said that tests at an accredited laboratory revealed that the phone exceeded the specific absorption rate (SAR) value mandated by the EU, which is four watts-per-kilogram (W/kg), when held in hand or in a trouser pocket. The "body" SAR - measured when the phone is in a jacket pocket or a bag at least 5mm away - was within the 2 W/kg limit, however.

Rospotrebnadzor is not considering such a ban. The regulator's spokesman said that Russia measures electromagnetic radiation using the PES scale rather than the SAR system, the results from which "cannot be compared."

The iPhone 12 was introduced in October 2020 and has continued to be popular due to a lower price point than the subsequent models. Apple disputes the French findings, claiming that the model has a SAR of 0.99 W/kg when measured by the EU standard.

However, the American tech giant has been accused of violating radiation standards before. In the US, Apple and Korean manufacturer Samsung were sued in 2019 after research found that the iPhone 8, iPhone X, and Galaxy S8 exceeded federal radiation limits by up to 500%.
