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.
