Abstract: A dosimeter includes a housing and a printed circuit board positioned within the housing. A silicon photomultiplier is operably connected to the printed circuit board. A scintillator formed of Ce-activated lithium aluminosilicate glass is positioned on the silicon photomultiplier. An optical coupling is positioned between the scintillator and the silicon photomultiplier, and an optical reflector surrounds the scintillator.

Abstract: A radiation dosimeter includes a first radiation detector configured to operate in a counting mode, and a second radiation detector configured to operate in a current mode. A processor is configured to calculate a first detected dose of the first radiation detector, a second detected dose of the second radiation detector, and a total dose value using the first detected dose and the second detected dose. An alarm indicates when the total dose value is above a predetermined level.

Abstract: A gamma radiation detecting device includes a scintillation detector that detects gamma radiation, the detector comprising a scintillation material that includes an element that creates, by neutron activation of the element, an isotope that emits gamma radiation, and a processor configured to monitor the gamma radiation emitted by the isotope, thereby detecting exposure of the gamma radiation detecting device to neutron radiation.
