An apparatus, comprising: at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: receive information on a power level of signals at least one radio transceiver of a user terminal has received from one or more external transmitters; determine information on a power level of signals transmitted by the at least one radio transceiver of the user terminal; determining information on a call connection and data transfer status of the user terminal; receive information from one or more sensors of the user terminal; characterised in that the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus further to: determine the model of the user terminal; transmit a query to a cloud server regarding the properties of the user terminal, the query comprising the model of the user terminal; receive from the cloud server information on the SAR value of the model of the user terminal; determine an amount of electromagnetic radiation the user of the user terminal is exposed to separately for call connections and data transfer traffic on the basis on the received and determined information and properties of the user terminal; compare the determined amount of radiation to a predetermined radiation value; and control a voice call and data transfer capabilities of the user terminal on the basis of the comparison. at least one processor;
