Abstract:
Described are a method and apparatus for determining based on motion data when an individual wearing a dosimeter is active. Also described are a method and apparatus for determining based on motion data whether an individual was wearing a dosimeter when the dosimeter was exposed to radiation. Also described are a method and apparatus for determining based on motion data whether a dosimeter was in a particular location when the dosimeter was exposed to radiation. Also described are a method and apparatus for determining based on motion data where on the body of an individual the individual was wearing a dosimeter when the dosimeter was exposed to radiation. Also described are a method and apparatus for determining based on motion data the probability that an individual is wearing a dosimeter that is assigned to the individual.

Abstract:
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. Furthermore, disclosed embodiments provide the use of MEMS and nanotechnology manufacturing techniques to encapsulate individual ionizing radiation sensor elements within a radiation attenuating material that provides a “filtration bubble” around the sensor element, the use of multiple attenuating materials (filters) around multiple sensor elements, and the use of a software algorithm to discriminate between different types of ionizing radiation and different radiation energy.
