Abstract

A device comprising: a substrate, a sensor package mounted on the substrate, and one or more filters, wherein the sensor package comprises one or more radiation sensors mounted therein, wherein each of the one or more filters is used to attenuate one or more types of radiation that enter an exposed side of each of the one or more radiation sensors at angle of up to +/−60 degrees with respect to a respective axial line through respective centers of each of the one or more radiation sensors.

Claims

1. A device comprising:

a substrate;

a sensor package mounted on the substrate; and

one or more filters,

wherein the sensor package comprises one or more radiation sensors mounted therein,

wherein each of the one or more filters filter one or more types of radiation that enter an exposed side of each of the one or more radiation sensors at angle of at least 60 degrees with respect to a respective axial line through respective centers of each of the one or more radiation sensors.

2. The device of claim 1, wherein the substrate is a printed circuit board (PCB) and the one or more radiation sensors are in electronic communication with circuitry of the PCB.

3. The device of claim 1, wherein the one or more filters are a single filter.

4. The device of claim 1, wherein the one or more filters are two or more filters.

5. The device of claim 1, wherein the one or more filters are mounted in a filter holder that is mounted on the substrate.

6. The device of claim 1, wherein the device comprises a radiation transmissive external case spaced from an exposed side of one filter of the one or more filters.

7. The device of claim 6, wherein the one or more filters are mounted in a filter holder that is mounted on the radiation transmissive external case.

8. The device of claim 6, wherein the one or more filters are mounted in a filter holder that is part of the radiation transmissive external case.

9. The device of claim 6, wherein the radiation transmissive external case is curved.

10. The device of claim 1, wherein the one or more radiation sensors are a single radiation sensor.

11. The device of claim 1, wherein the one or more radiation sensors are two radiation sensors.

12. A device comprising:

a substrate;

a first sensor package mounted on the substrate;

one or more first filters; and

a second sensor package mounted on the substrate

wherein the first sensor package comprises one or more first radiation sensors mounted therein,

wherein the second sensor package comprises one or more second radiation sensors mounted therein,

wherein each of the one or more first filters filter one or more types of radiation that enter an exposed side of each of the one or more first radiation sensors at angle of at least 60 degrees with respect to a respective axial line through respective centers of each of the one or more first radiation sensors.

13. The device of claim 12, wherein the substrate is a printed circuit board (PCB) and the one or more first radiation sensors the one or more second radiation sensors are in electronic communication with circuitry of the PCB.

14. The device of claim 12, wherein the one or more first filters are a single filter.

15. The device of claim 12, wherein the one or more first filters are two or more filters.

16. The device of claim 12, wherein the one or more first filters are mounted in a filter holder that is mounted on the substrate.

17. The device of claim 12, wherein the device comprises a radiation transmissive external case spaced from an exposed side of one first filter of the one or more first filters.

18. The device of claim 17, wherein the radiation transmissive external case has window configured to allow radiation to pass through the window and enter the second sensor package through an exposed side of the sensor package and exposed the one or more second radiation sensors to radiation through respective exposed sides of the one or more second radiation sensors.

19. The device of claim 18, wherein at least one or more first radiation sensors is a high dose radiation sensor and wherein at least one of the one or more second radiation sensors is a low dose radiation sensor.

20. The device of claim 18, wherein the second sensor package is mounted indirectly on the substrate and wherein the second sensor package is mounted on a spacer that spaces the second sensor package from the substrate.

21. The device of claim 18, wherein the radiation transmissive external case is curved.

22. The device of claim 17, wherein the one or more first filters are mounted in a first filter holder that is mounted on the radiation transmissive external case.

23. The device of claim 17, wherein the one or more first filters are mounted in a first filter holder that is part of the radiation transmissive external case.

24. The device of claim 17, wherein the radiation transmissive external case is curved.

25. The device of claim 12, wherein the one or more first radiation sensors are a single radiation sensor.
