Abstract
A subsurface continuous radioisotope environmental monitor that provides a continuous monitoring of the possible presence of radioactive species in subsurface groundwater. The detector and all supporting system elements are specifically constructed and equipped to be permanently mounted in a well or borehole to continuously detect and record radiation decay of radioactive species that are borne by subsurface water flow to that sampling area. The system operates by placing a detection element in a housing such that subsurface water that reaches the bore or well can flow in contact with the detection element. The system can employ several detection modes and materials. The detector includes SiPMs operating in a coincidence spectroscopy configuration to significantly reduce spurious signals due to thermal noise as well as increasing the total amount of signals collected.
