Radiation detection apparatus having an analyzer within a housing
A radiation detection apparatus can include a scintillator to emit scintillating light in response to absorbing radiation; a photosensor to generate an electronic pulse in response to receiving the scintillating light; an analyzer to determine a characteristic of the radiation; and a housing that contains the scintillator, the photosensor, and the analyzer, wherein the radiation detection apparatus to is configured to allow functionality be changed without removing the analyzer from the housing. The radiation detection apparatus can be more compact and more rugged as compared to radiation detection apparatuses that include a photomultiplier tube.
