Moon is an auspicious environment for the study of Galactic cosmic rays (GCR) and Solar particle events (SEP) due to absence magnetic field atmosphere. The same characteristics raise radiation risk human presence in orbit around it or at lunar surface. secondary (albedo) resulting from interaction primary with soil adds extra factor, because neutrons are produced, but also can be exploited composition. In this paper, design a comprehensive monitor package tailored presented. detector, named LURAD, will perform spectroscopic measurements protons, electrons, heavy ions, as well gamma-rays, neutrons. A microdosimetry subsystem foreseen which provide LET(Si) spectra wide dynamic range flux SPE GCR, detection biological dose protection astronauts. LURAD leverages on following key enabling technologies: (a) Fully depleted Si monolithic active pixel sensors; (b) Scintillators read by silicon photomultipliers (SiPM); (c) Silicon Insulator (SOI) These technologies promise miniaturization mass reduction state-of-the-art performance. instrument's presented, Monte Carlo feasibility identification kinetic energy determination discussed
