We measured an average total absorbed dose rate in silicon of 13.2 ± 1 μGy/hour ... LND measured an average dose equivalent of 1369 μSv/day on the surface of the Moon
{{cite journal}}: CS1 maint: multiple names: authors list (link){{cite journal}}: CS1 maint: multiple names: authors list (link)Using the 329 optimal passes, global maps of the lunar crustal magnetic field are constructed at 30 and 40 km.
The history of the lunar magnetic field is a longstanding controversy.
Together, these data indicate that the Moon did not have a long-lived core dynamo.
No single dynamo mechanism proposed thus far can explain the strong fields inferred for the period before 3.56 Ga while also allowing the dynamo to persist in such a weakened state beyond ~2.5 Ga. Therefore, our results suggest that the dynamo was powered by at least two distinct mechanisms operating during early and late lunar history.
It has now been established that a dynamo magnetic field likely existed on the Moon from at least 4.5 billion to 3.56 billion years ago, with an intensity similar to that at the surface of Earth today.
However, paleomagnetic measurements of Apollo samples indicate that the Moon once generated a core dynamo with surface field intensities of several tens of microtesla (comparable to that of Earth today) during the period 4.25 to 3.56 billion years (Ga) ago (2–7). Following this high-field epoch, the field declined by at least an order of magnitude by 3.2 Ga ago (8) and persisted in a weakened state (~5 μT) until at least 2.5 Ga ago (9).
Models of conventional dynamos driven by thermal or compositional convection have had difficulty reproducing the existence and apparently long duration of the lunar dynamo.

The moon's Hill sphere has a radius of 60,000 kilometres, about one-sixth of the distance between it and Earth.
