Abstract
A personal radiation dosimeter may comprise a housing that is substantially light-impermeable. The housing contains a radiation energy sensitive component (RESC) that is transported by a user. A reader has ingress and egress for the housing, and an internal stimulation light to photo-stimulate the RESC. An internal photosensor senses photons from the RESC after photo-stimulation and generates a signal. The photosensor may convert and amplify the RESC signal into a signal corresponding to the amount of radiation. A processing circuit may be used to assess an amount of radiation incident on the RESC based on the signal. In addition, the reader may contain a reset light to reset the RESC for reuse after the amount of radiation is detected.
Claims30
A personal radiation dosimeter, comprising:
- a housing that is substantially light-impermeable and contains a radiation energy sensitive component (RESC), and the housing is configured to be transported by a user;
- and
- a reader having ingress and egress for the housing, a stimulation light configured to photo-stimulate the RESC, a photosensor configured to sense photons resulting from photo-stimulation and generate a signal, a processing circuit configured to assess an amount of radiation incident on the RESC based on the signal, and a reset light configured to reset the RESC for reuse after the amount of radiation is determined.

A personal radiation dosimeter, comprising:
- a carrier that is substantially light-impermeable and contains a storage phosphor plate (SPP) that detects radiation, and the carrier is configured to be carried by a user;
- and
- a reader having ingress and egress for the carrier, a stimulation light configured to photo-stimulate the SPP, a photosensor configured to sense photons from the SPP resulting from photo-stimulation and generate a signal, a processing circuit configured to assess an amount of radiation incident on the SPP based on the signal, and a reset light configured to reset the SPP for reuse after the amount of radiation is determined.

A method of radiation detection, comprising:
- (a) exposing a radiation detector to a dosage of radiation and storing at least a portion of the energy deposited in the radiation detector;
- (b) putting the radiation detector in a reader;
- (c) stimulating the radiation detector to release photons in proportion to the radiation dosage;
- (d) sensing the released photons;
- (e) determining the radiation dosage in proportion to the released photons;
- (f) displaying the radiation dosage;
- (g) erasing the radiation detector with the reader;
- (h) removing the radiation detector from the reader;
- and
- (i) reusing the radiation detector for detecting another dosage of radiation.
