Ray take a look at a neutrino detector and THINK.

Pay special attention to the fact that they are typicall sited
underground to avoid the scintilation detectors being triggered
by sources other than neutrinos.

The Japanese KamLAND detector is fairly typical. It consists of an
18 m diameter stainless steel spherical vessel fitted with 1,879
photomultiplier
tubes mounted on the inner surface. Inside the sphere is a 13 m
diameter nylon
balloon filled with of 1,000 metric tons}} of mineral oil, benzene and
fluorescent
chemicals. Outside of the balloon, non-scintillating, highly purified
oil provides
buoyancy for the balloon and acts as a shield against external
radiation. Surrounding the stainless steel vessel is a water Cherenkov
detector, which acts as a muon veto counter and provides shielding
from radioactivity in the rock.

The whole assembly is sited in a drift mine deep inside a mountain

Lots of luck putting that on a ship :)

No way.

However, reread froggie's post, which seems to indicate that there's
a more compact way - but if they told you, they'd have to kill you.
