Abstract
Radiation detection is disclosed. A radiation detection package includes a radio-photoluminescent glass (RPLG), an EMR source and a photodetector. The EMR source includes an input lead, and is configured to emit first energy in a predetermined band of EMR in a downstream direction toward the RPLG in response to receipt of an input signal on the input lead of the EMR source. The photodetector has an output lead, and is configured to detect second energy that is emitted by the RPLG in an emission band of EMR in response to the receipt of the first energy in the predetermined band of EMR, and generate a first output signal on the output lead indicative of an amount of the second energy.
Claims26
A radiation detection package (RDP) comprising:
- a radio-photoluminescent glass (RPLG);
- an electromagnetic radiation (EMR) source comprising an input lead, and configured to emit first energy in a predetermined ultraviolet (UV) band of EMR in a downstream direction toward the RPLG in response to receipt of an input signal on the input lead of the EMR source;
- and
- a photodetector having an output lead, and configured to detect second energy that is emitted by the RPLG in a UV emission band of EMR in response to the receipt of the first energy in the predetermined UV band of EMR, and generate a first output signal on the output lead indicative of an amount of the second energy.
A printed circuit board (PCB), comprising:
- a plurality of radiation detection packages coupled to a surface of the PCB, the plurality of radiation detection packages located at different respective locations on the surface of the PCB, each radiation detection package comprising:
- a radio-photoluminescent glass (RPLG);
- an electromagnetic radiation (EMR) source comprising an input lead, and configured to emit first energy in a predetermined ultraviolet (UV) band of EMR in a downstream direction toward the RPLG in response to receipt of an input signal on the input lead of the EMR source;
- and
- a photodetector having an output lead, and configured to detect second energy that is emitted by the RPLG in a UV emission band of EMR in response to the receipt of the first energy in the predetermined UV band of EMR, and generate a first output signal on the output lead indicative of an amount of the second energy;
- and
- a processor comprising a controller coupled to the plurality of radiation detection packages, and configured to:
- receive the output signal from each of the plurality of radiation detection packages;
- and
- make a determination that the output signal from any of the plurality of radiation detection packages exceeds a predetermined threshold value.
A method, comprising:
- receiving, by an electromagnetic (EMR) source, a first input signal on an EMR input lead;
- in response to receipt of the first input signal, emitting first energy in a predetermined ultraviolet (UV) band of EMR in a downstream direction toward a radio-photoluminescent glass (RPLG) that is fixed with respect to the EMR source;
- receiving, by a photodetector fixed with respect to the RPLG and having a photodetector output lead, a second input signal;
- detecting, by the photodetector, second energy that is emitted by the RPLG in an a UV emission band of EMR in response to the receipt of the first energy in the predetermined UV band of EMR;
- and
- emitting, by the photodetector, a first output signal on the photodetector output lead indicative of an amount of the second energy.
A radiation detection package (RDP) comprising:
- a radio-photoluminescent glass (RPLG);
- an electromagnetic radiation (EMR) source comprising an input lead, and configured to emit first energy in a predetermined band of EMR in a downstream direction toward the RPLG in response to receipt of an input signal on the input lead of the EMR source;
- a photodetector having an output lead, and configured to detect second energy that is emitted by the RPLG in an emission band of EMR in response to the receipt of the first energy in the predetermined band of EMR, and generate a first output signal on the output lead indicative of an amount of the second energy;
- and
- a reflector;
- and wherein:
- the RPLG has a first side and a second side;
- the EMR source and the photodetector are positioned with respect to the first side of the RPLG;
- the reflector is positioned with respect to the second side of the RPLG;
- the EMR source is configured to emit the first energy in the predetermined UV band of EMR in the downstream direction toward the first side of the RPLG;
- and
- the reflector is configured to reflect energy emitted from the second side by the RPLG in response to the first energy in the downstream direction toward a different portion of the second side of the RPLG and back through the RPLG in the downstream direction toward the photodetector.
