Abstract
Devices, methods, and related systems are described for measuring a property of a fluid, including density, in a subterranean environment. A device includes a pressure housing having one or more windows formed in the pressure housing and a flow device arranged in the pressure housing for the fluid to flow through the flow device. Further, a radiation source is mounted within the pressure housing approximate a first source window configured to generate particles into the fluid. The device includes a detector supported by the pressure housing and positioned approximate a first detector window of the one or more windows. The first detector window is located between the detector and the flow device. The detector can be a solid state beta particle detector with a wide band gap, such as the diamond detector, and the radiation source can be a beta particle source, such as a strontium 90 source.
