System for wireless, motion and position-sensing, integrating radiation sensor and energy harvester for occupational and environmental dosimetry

摘要

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.

1. A method comprising the following steps:
(a) determining whether an individual was wearing a dosimeter during a monitored period based upon motion and time data obtained from the dosimeter, and (b) determining whether an individual was wearing the dosimeter when the dosimeter was exposed to one or more radiation sources based upon measured radiation dosage data for the dosimeter, motion data for the dosimeter, time data associated with the radiation dosage data, and time data associated with the motion data, (c) reporting whether the dosimeter was worn during a monitored period via display on a visual display device and/or via saving whether the individual was wearing a dosimeter when the dosimeter was exposed to one or more radiation sources to a storage medium, and (d) reporting whether the individual was wearing a dosimeter when the dosimeter was exposed to one or more radiation sources via display on a visual display device and/or via saving whether the individual was wearing a dosimeter when the dosimeter was exposed to one or more radiation doses to a storage medium; wherein the dosimeter comprises one or more motion sensors for generating the motion data.
