Assessment of natural radioactivity in bottled mineral water from Brazil
Brazilian Journal of Radiation Sciences, 2022 The approach taken in the WHO Guidelines for controlling radiological hazards in public water supplies has two stages. The first is an initial screening for gross alpha and beta activity to determine whether the activity concentrations are below levels ...

Detection of liquid xenon scintillation light with a Silicon Photomultiplier [PDF]
, 2005 We have studied the feasibility of a silicon photomultiplier (SiPM) to detect liquid xenon (LXe) scintillation light. The SiPM was operated inside a small volume of pure LXe, at -95 degree Celsius, irradiated with an internal Am-241 alpha source.
