A hand-held mobile communication device, such as smart telephone, incorporating sensors and signal conditioning modules for measuring signals from external sources of electromagnetic radiation (EMR) in the low, radio, ultraviolet, and infrared spectral ranges. These include the detector for receiving and monitoring electromagnetic fields originating from various external sources of radiation that pose potential health hazards or may interfere with various electronic devices. The mobile phone equipped with such sensors could alternate between communication and monitoring functions. Other integrated EMR sensors are a photodiode for the ultraviolet detection to monitor the users sun exposure and a thermopile for non-contact measurement of temperature of humans or inanimate objects. This infrared sensor in combination with a photographic digital camera and a pattern recognition signal processing allows measuring temperatures at specific locations and from optimal distances to the surface of the object to enhance accuracy of non-contact temperature measurements.
