Alpha-ray detector (ARD) onboard SELENE was designed for detecting α-particles emitted by Rn-222 emanated on the lunar surface and its descendent nuclear species Po-210. Distribution and variation of radon gas measured by the α-particle signal is expected to provide information on the subsurface uranium distribution, crustal structures including faults, and behavior of the thin atmosphere of the moon. In this paper, we describe the flow of ARD data processing and a method to derive the α-particle intensity distribution utilizing the angular response of the detector which is applied to the radon α-particle observations for the first time. The method improves the resolution of the α-particle intensity map and enables detailed comparison with the geographical features of the lunar surface.
