Claims

1-16. -16. (canceled)

17. A device comprising:

a dosimeter for measuring one or more doses of radiation; and

a radio frequency identification (RFID) tag comprising;

an antenna for communicating with an RFID tag reader, and

a non-volatile memory for storing data,

wherein the dosimeter comprises one or more optically stimulated luminescence (OSL) sensors,

wherein the dosimeter is configured to have adjusted readout radiation dose data for the dosimeter written to and stored on the non-volatile memory by a current dosimeter reader that reads current radiation dose data from the one or more OSL sensors,

wherein the dosimeter is configured to store historical data,

wherein the dosimeter is configured to have the historical data read by the current dosimeter reader,

wherein the adjusted radiation dose data comprises current readout radiation dose data that has been adjusted based on the historical data read by the current dosimeter reader,

wherein the historical data comprises radiation dose data for the dosimeter that has been readout by one or more prior dosimeter readers and written to the non-volatile memory by one or more of the one or more prior dosimeter readers.

18. The device of claim 17, wherein the current dosimeter reader is one of the one or more prior dosimeter readers.

19. The device of claim 17, wherein the historical data comprises calibration data for one or more of the one or more of the OSL sensors.

20. The device of claim 17, wherein the dosimeter is part of a badge that may be worn by an individual.

21. The device of claim 17, wherein the historical data comprises identification information for a model type of the dosimeter.

22. The device of claim 17, wherein the historical data comprises a dosimeter serial number for the dosimeter.

23. The device of claim 17, wherein the historical data comprises information regarding an assignment of the dosimeter to an individual.

24. The device of claim 23, wherein the historical data comprises an identification number for the individual to whom the dosimeter is assigned.

25. The device of claim 23, wherein the historical data comprises date and time information regarding the assignment of the dosimeter to an individual.

26. The device of claim 17, wherein the historical data comprises information for estimating a buildup of background radiation in the dosimeter.

27. The device of claim 26, wherein the historical data comprises date and time information for estimating a buildup of background radiation in the dosimeter.

28. The device of claim 17, the historical data comprises date and time information for when the dosimeter has been read out.

29. The device of claim 17, wherein the historical data comprises a total dose of radiation to which the dosimeter has been exposed.

30. The device of claim 17, wherein the historical data comprises a total dose of x-rays and gamma rays to which the dosimeter has been exposed.

31. The device of claim 17, wherein the historical data comprises a total dose of neutrons to which the dosimeter has been exposed.

32. The device of claim 17, wherein the one or more prior dosimeter readers have read one or more radiation dosage measurements for the dosimeter, and wherein the historical data comprises a serial number of the dosimeter reader used to read a last radiation dosage measurement for the dosimeter.

33. The device of claim 17, wherein the dosimeter comprises two or more optically stimulated luminescence (OSL) sensors.

34. The device of claim 17, wherein the historical data comprises reader quality control data depicting operability of a dosimeter reader that is being used to read the one or more OSL sensors.

35. A device comprising:

a dosimeter for measuring one or more doses of radiation; and

a radio frequency identification (RFID) tag comprising;

an antenna for communicating with an RFID tag reader, and a non-volatile memory for storing data,

wherein the dosimeter comprises one or more optically stimulated luminescence (OSL) sensors, and

wherein the non-volatile memory of the RFID tag has data stored therein that comprises reader quality control data depicting operability of a current dosimeter reader that is being used to read the one or more OSL sensors,

wherein the dosimeter is configured to have adjusted readout radiation dose data for the dosimeter written to and stored on the non-volatile memory by the current dosimeter reader that reads current radiation dose data from the one or more OSL sensors,

wherein the dosimeter is configured to store historical data,

wherein the dosimeter is configured to have the historical data read by the current dosimeter reader,

wherein the adjusted radiation dose data comprises current readout radiation dose data that has been adjusted based on the historical data read by the current dosimeter reader,

wherein the historical data comprises radiation dose data for the dosimeter that has been readout by one or more prior dosimeter readers and written to the non-volatile memory by one or more of the one or more prior dosimeter readers.

36. The device of claim 35, wherein the current dosimeter reader is one of the one or more prior dosimeter readers.
