Abstract

Dosimeters with wireless communications capability, upon actuation, communicate with a cell phone or other data capture and relay device (DCRD) with an application that allows communication with the dosimeters. The cell phone or other DCRD is a single device or part of an ad hoc network. The cell phone or other DCRD, once it receives raw data from a dosimeter, relays the data to a central station using mobile telephone or Wi-Fi or other communications networks. The data is processed at the central station, and available over the internet or cell phone.

Claims

1. A dosimeter, comprising:

a radiation detector;

a control circuit connected to the radiation detector;

a normally dormant communications circuit connected to the control circuit;

a power supply connected to the control circuit;

a wakeup actuator connected to the control circuit for actuating the communications circuit at selected times only when it is desired to transmit dosimeter data from the dosimeter;

wherein

the communications circuit has wireless communications capability for transmitting the dosimeter data, the wireless communications capability being normally dormant;

wherein the control circuit comprises a memory or a register to store the dosimeter data that have been transmitted from the dosimeter;

the communications circuit connected to the control circuit for transmitting the dosimeter data from the radiation detector in the form of a packet of data, said packet of data including dosimeter serial number and radiation data comprising an output of the radiation detector as well as a transmission sequence number from which a central station receiving the dosimeter data transmitted from the communications circuit can determine that the packet of data has not been received by the central station.

2. The dosimeter of claim 1, wherein the wakeup actuator comprises programmable firmware for configuring wakeup intervals to periodically transmit the dosimeter data.

3. The dosimeter of claim 1, wherein the packet of data also includes battery condition or dosimeter location.

4. The dosimeter of claim 1, wherein the communications circuit is provided for communicating with the central station via a wireless data capture and relay device acting as a wireless communications link between the dosimeter and the central station.

5. The dosimeter of claim 1, wherein the radiation detector is a direct ion storage (DIS) detector.

6. A dosimeter, comprising:

a radiation detector;

a control circuit connected to the radiation detector;

a normally dormant communications circuit connected to the control circuit;

a power supply connected to the control circuit;

a wakeup actuator connected to the control circuit for actuating the communications circuit at selected times only when it is desired to transmit dosimeter data from the dosimeter;

wherein

the communications circuit has wireless communications capability for transmitting the dosimeter data, the wireless communications capability being normally dormant;

wherein the control circuit comprises a memory or a register to store the dosimeter data that have been transmitted from the dosimeter;

the communications circuit connected to the control circuit for transmitting the dosimeter data from the radiation detector in the form of a packet of data, said packet of data including dosimeter serial number and radiation data comprising an output of the radiation detector as well as a timing data from which a central station receiving the dosimeter data transmitted from the communications circuit can determine that the packet of data has not been received by the central station.

7. The dosimeter of claim 6, wherein the wakeup actuator comprises programmable firmware for configuring wakeup intervals to periodically transmit the dosimeter data.

8. The dosimeter of claim 6, wherein the packet of data also includes battery condition or dosimeter location.

9. The dosimeter of claim 6, wherein the communications circuit is provided for communicating with the central station via a wireless data capture and relay device acting as a wireless communications link between the dosimeter and the central station.

10. The dosimeter of claim 6, wherein the radiation detector is a direct ion storage (DIS) detector.

11. An apparatus for collecting dosimeter data at a central station, comprising:

a radiation detector,

a control circuit connected to the radiation detector;

a normally dormant communications circuit connected to the control circuit;

a power supply connected to the control circuit; and

a wakeup actuator connected to the control circuit for actuating the communications circuit at selected times only when it is desired to transmit the dosimeter data from a dosimeter;

wherein

the communications circuit has wireless communications capability for transmitting the dosimeter data, the wireless communications capability being normally dormant;

wherein the communications circuit is arranged for transmitting the dosimeter data from the radiation detector in the form of a packet of data, said packet of data including dosimeter serial number and radiation data comprising an output of the radiation detector, as well as a transmission sequence number or timing data from which the central station receiving the dosimeter data transmitted from the communications circuit can determine that the packet of data has not been received;

wherein the control circuit comprises a memory or a register to store the dosimeter data that have been transmitted from the dosimeter.

12. The apparatus of claim 11, wherein the wakeup actuator comprises programmable firmware for configuring wakeup intervals to periodically transmit the dosimeter data.

13. The apparatus of claim 11, wherein the packet of data also includes battery condition or dosimeter location.

14. The apparatus of claim 11, wherein the communications circuit is provided for communicating with the central station via a wireless data capture and relay device acting as a wireless communications link between the dosimeter and the central station.

15. apparatus of claim 11, wherein the radiation detector is a direct ion storage (DIS) detector.
