Abstract

Described is a dosimeter sled comprising: one or more optically stimulated luminescence (OSL) sensors mounted in the dosimeter sled and an RFID tag comprising an antenna for communicating with an RFID tag reader and a non-volatile memory for storing data therein.

Claims (41)

1. A device comprising:

a dosimeter sled comprising:

one or more optically stimulated luminescence (OSL) sensors mounted in the dosimeter sled; and

an RFID tag comprising:

an antenna for communicating with an RFID tag read/writer, and

a non-volatile memory for storing data.

2. The device of claim 1 , wherein the dosimeter sled is separable from the dosimeter.

3. The device of claim 1 , wherein the non-volatile memory of the RFID tag has data stored therein.

4. The device of claim 1 , wherein the data stored in the non-volatile memory of the RFID tag comprises identification information for a model type of the dosimeter.

5. The device of claim 1 , wherein the data stored in the non-volatile memory of the RFID tag comprises a unique identifier for the dosimeter.

6. The device of claim 1 , wherein the data stored in the non-volatile memory of the RFID tag comprises data information regarding the assignment of the dosimeter to an individual.

7. The device of claim 6 , wherein the data stored in the non-volatile memory of the RFID tag comprises identification number for the individual to whom the dosimeter is assigned.

8. The device of claim 6 , wherein the data stored in the non-volatile memory of the RFID tag comprises time information regarding the assignment of the dosimeter to an individual.

9. The device of claim 1 , wherein the data stored in the non-volatile memory of the RFID tag comprises calibration data for each of the one or more OSL sensors.

10. The device of claim 1 , wherein the data stored in the non-volatile memory of the RFID tag comprises data information for estimating a build up of background radiation in the dosimeter.

11. The device of claim 10 , wherein the data stored in the non-volatile memory of the RFID tag comprises time information for estimating a build up of background radiation in the dosimeter.

12. The device of claim 1 , wherein the data stored in the non-volatile memory of the RFID tag comprises a total dose of radiation to which the dosimeter has been exposed.

13. The device of claim 1 , wherein the data stored in the non-volatile memory of the RFID tag comprises a total dose of x-rays and gamma rays to which the dosimeter has been exposed.

14. The device of claim 1 , wherein the data stored in the non-volatile memory of the RFID tag comprises a total dose total dose of neutrons to which the dosimeter has been exposed.

15. The device of claim 1 , wherein the data stored in the non-volatile memory of the RFID tag comprises reader quality control data depicting the operability of a dosimeter reader that is being used to read the one or more OSL sensors.

16. The device of claim 1 , wherein the data stored in the non-volatile memory of the RFID tag comprises the serial number of the dosimeter reader used to perform the last dosage measurement.

17. A device comprising:

a dosimeter sled comprising:

one or more optically stimulated luminescence (OSL) sensors mounted in the dosimeter sled; and

an RFID tag comprising:

an antenna for communicating with an RFID tag read/writer, and

a non-volatile memory for storing data, wherein the data stored in the non-volatile memory of the RFID tag comprises at least data information regarding the assignment of the dosimeter to an individual; and

wherein the data stored in the non-volatile memory of the RFID tag comprises calibration data for each of the one or more OSL sensors.

18. The device of claim 17 , wherein the dosimeter sled is a part of a dosimeter, and wherein the dosimeter sled is separable from the dosimeter.

19. The device of claim 17 , wherein the non-volatile memory of the RFID tag has data stored therein.

20. The device of claim 17 , wherein the data stored in the non-volatile memory of the RFID tag comprises identification information for a model type of the dosimeter.

21. The device of claim 17 , wherein the data stored in the non-volatile memory of the RFID tag comprises a unique identifier for the dosimeter.

22. The device of claim 17 , wherein the data stored in the non-volatile memory of the RFID tag comprises identification number for the individual to whom the dosimeter is assigned.

23. The device of claim 17 , wherein the data stored in the non-volatile memory of the RFID tag comprises time information regarding the assignment of the dosimeter to an individual.

24. The device of claim 17 , wherein the data stored in the non-volatile memory of the RFID tag comprises data information for estimating a build up of background radiation in the dosimeter.

25. The device of claim 17 , wherein the data stored in the non-volatile memory of the RFID tag comprises time information for estimating a build up of background radiation in the dosimeter.

26. The device of claim 17 , wherein the data stored in the non-volatile memory of the RFID tag comprises a total dose of radiation to which the dosimeter has been exposed.

27. The device of claim 17 , wherein the data stored in the non-volatile memory of the RFID tag comprises a total dose of x-rays and gamma rays to which the dosimeter has been exposed.

28. The device of claim 17 , wherein the data stored in the non-volatile memory of the RFID tag comprises a total dose total dose of neutrons to which the dosimeter has been exposed.

29. The device of claim 17 , wherein the data stored in the non-volatile memory of the RFID tag comprises reader quality control data depicting the operability of a dosimeter reader that is being used to read the one or more OSL sensors.

30. The device of claim 17 , wherein the data stored in the non-volatile memory of the RFID tag comprises the serial number of the dosimeter reader used to perform the last dosage measurement.
