floor, away from outside walls and windows.

With doors, furniture and appliances, plus stacks of other shielding
material, you can create an enclosure large enough to live in for a
short time. If possible, use boxes filled with sand or earth as
shielding material, and fill drawers and trunks with sand or earth.

If there is not room for the shielding material in the limited space of
a closet or small room, you can place the material on the other sides of
the walls, or on the floor overhead.


BOATS AS IMPROVISED SHELTERS

If no better fallout protection is available, a boat with an enclosed
cabin could be used. However, in addition to emergency supplies such as
food, drinking water and a battery-powered radio, you should have aboard
the items you would need (a broom, bucket, or pump-and-hose) to sweep
off or flush off any fallout particles that might collect on the boat.

The boat should be anchored or cruised slowly at least 200 feet
offshore, where the water is at least 5 feet deep. This distance from
shore would protect you from radioactive fallout particles that had
fallen on the nearby land. A 5-foot depth would absorb the radiation
from particles falling into the water and settling on the bottom.

If particles drift down on the boat, stay inside the cabin most of the
time. Go outside now and then, and sweep or flush off any particles that
have collected on the boat.
