Scientists recently discovered high levels of heat beneath the surface of a suspected volcanic formation on the Moon, using data from China’s lunar rovers Chang’e-1 and Chang’e-2. Compton Bercovici.
The presence of these hot spots suggests the underlying granite may contain radioactive elements like thorium and uranium undergoing decay.
Research estimates that the background radiation level on the Moon is about 0.3 millisieverts per year.
This is relatively low compared to the approximately 6 millisieverts of natural radiation every person on Earth receives annually.
However, being on the Moon exposes us to other sources of radiation like galactic cosmic rays, high-energy solar particles, and neutron and gamma rays from lunar soil.
The average maximum radiation dose from all these sources is estimated to exceed 400 millisieverts per year, potentially rising higher during powerful solar flares.
Despite the Moon’s low natural radioactivity levels, its overall ionizing radiation environment is considered hostile.
