Abstract<\/strong><\/p>\n\n\n\n

Sea-level cosmic ray flux was measured anew in Iligan City using two plastic scintillators, each with an area of 100 \u00d7 10 cm\u00b2, stacked vertically with a spacing of 150 cm. Each scintillator was individually coupled to a Hamamatsu photomultiplier tube, which, when supplied with high voltage, formed a detection\u2013amplification system. This detector assembly was then connected to Nuclear Instrumentation Modules (NIM) to discriminate and count coincident signals over a fixed time interval during the months of August\u2013September 1999 at the MSU-IIT High Energy Physics (HEP) Laboratory.
Data show no significant difference between the measured average nighttime and daytime cosmic ray fluxes. Furthermore, the average hourly and daily fluxes remained constant throughout the measurement period. These results are consistent with the first measurements of cosmic ray flux conducted at the same laboratory in 1999 using an entirely different detector\u2013electronics assembly. The measured values are also in good agreement with Monte Carlo simulations and internationally accepted predicted values.<\/p>\n<\/div>\n\n\n\n
