Wireless, motion and position-sensing, integrating radiation sensor for occupational and environmental dosimetry


Described is a radiation dosimeter including multiple sensor devices (including one or more passive integrating electronic radiation sensor, a mems accelerometers, a wireless transmitters and, optionally, a gps, a thermistor, or other chemical, biological or emf sensors) and a computer program for the simultaneous detection and wireless transmission of ionizing radiation, motion and global position for use in occupational and environmental dosimetry. The described dosimeter utilizes new processes and algorithms to create a self-contained, passive, integrating dosimeter.
