Radiation Dose Monitor Experiment (RADOM-7 – BAS)
The Radiation Dose Monitor Experiment, from the Bulgarian Academy of Sciences, mapped the radiation environment around the Moon. It characterised the particle flux and deposited-dose rates in lunar orbit, produced by galactic cosmic rays and solar energetic particles.
RADOM-7 was among the first instruments activated, tested on 16 November 2008, and operated throughout the mission. Its measurements of the lunar radiation environment remain valuable for planning the radiation protection of future crewed lunar missions — including India's goal of landing an astronaut on the Moon by 2040.
