Liquid scintillators are widely used in various fields because they give a high light yield. In addition, the development of stable liquid scintillator for particle detectors and medical applications is very important. This paper proposes a new base material, a mixture of alcohol and water, for a liquid scintillator. The development of this alcohol-based liquid scintillator and the experimental result for various physical and optical properties are described. Until now, R\&D studies on such detectors or no market products of this type have been available. Thus, room exists for improvement. Therefore, various possibilities for detection solutions were studied by varying the mixing ratio of each component constituting the liquid scintillator. Finally, as an example of usage in medical physics, a range (=beam-path-length) measurement using an electron beam is briefly described. The measurement results obtained by changing the energy of the incident electron beam were compared with Monte Carlo simulation, Novalis-Tx and the phantom results.
