Exemplary methods, systems and components enable detection and/or monitoring and/or control of electromagnetic radiation (EMR) exposure of target body-related portions of a user operating a telecommunication device. In some embodiments a risk-assessment output is provided based on a safety threshold or predetermined intrusion level of EMR exposure. A further aspect may include interaction with external EMR sources regarding possible modification of emissions as well as possible arrangements for other types of remedial action. Some embodiments may provide travel route mapping data indicative of EMR source locations and/or irradiation values in a given locale.
