Devices only receive the state environmental label “Blue Angel” if the SAR value is no more than 0.5 watts per kilogram.
The BfS constantly publishes a list of standardized SAR test values online. Parents in particular who want to buy a suitable device for their children can do so here Tell up front whether manufacturers are also taking aspects of radiation protection into account in their products,” said BfS President Inge Paolini.
