Radiation Environment In Earth-Moon Space: Results From RADOM Experiment Onboard Chandrayaan-1

TL;DR

This paper presents findings from the RADOM experiment onboard Chandrayaan-1, which monitored the radiation environment in near-Earth and lunar space, providing valuable data on radiation levels and spectra during the mission.

Contribution

It provides the first comprehensive measurement of radiation in lunar orbit using the RADOM dosimeter-spectrometer onboard Chandrayaan-1.

Findings

Measured total absorbed dose in lunar orbit

Characterized energy spectrum of high-energy particles

First in-situ radiation data for lunar space environment

Abstract

The Radiation Monitor (RADOM) payload is a miniature dosimeter-spectrometer onboard Chandrayaan-1 mission for monitoring the local radiation environment in near-Earth space and in lunar space. RADOM measured the total absorbed dose and spectrum of the deposited energy from high energy particles in near-Earth space, en-route and in lunar orbit. RADOM was the first experiment to be switched on soon after the launch of Chandrayaan-1 and was operational till the end of the mission. This paper summarizes the observations carried out by RADOM during the entire life time of the Chandrayaan-1 mission and some the salient results.
