Solar storm radiation on Moons nightside

[Harri Tavaila]

It is well known that charged particle radiation poses a significant
risk to all manned spaceflights outside Earths magnetic field.

It is also clear that by its nature this radiation can not be complitely
blocked by simple line of sight shielding: with small scale geometry
there is little shadowing effect.

However it would seem natural to expect sufficiently large masses to
create some shelter. Therefore one wonders if nightside of the Moon or
larger asteroids would provide protection even from worst solar storms?

Intuitively it would appear to be associated with the temperature of the
plasma and its general velocity. BOE calculations are not promising but
it would be nice to have this confirmed by some official source.
