A nuclear blast
is an explosion with intense light and heat, a
damaging pressure wave and widespread radioactive
material that can contaminate the air, water and
ground surfaces for miles around. During a nuclear
incident, it is important to avoid radioactive
material, if possible. While experts may predict
at this time that a nuclear attack is less likely
than other types, terrorism by its nature is
unpredictable. If there
is advanced warning of an attack:
Take cover immediately, as far below ground as
possible, though any shield or shelter will help
protect you from the immediate effects of the
blast and the pressure wave.
If there
is no warning:
-
Quickly assess
the situation.
-
Consider if
you can get out of the area or if it would
be better to go inside a building to limit
the amount of radioactive material you are
exposed to.
-
If you take
shelter go as far below ground as possible,
close windows and doors, turn off air
conditioners, heaters or other ventilation
systems. Stay where you are, watch TV,
listen to the radio, or check the Internet
for official news as it becomes available.
-
To limit the
amount of radiation you are exposed to,
think about shielding, distance and time.
-
Shielding:
If you have a thick shield between
yourself and the radioactive materials
more of the radiation will be absorbed,
and you will be exposed to less.
-
Distance: The
farther away you are away from the blast
and the fallout the lower your exposure.
-
Time: Minimizing
time spent exposed will also reduce your
risk.
Use available
information to assess the situation. If there is a
significant radiation threat, health care
authorities may or may not advise you to take
potassium iodide. Potassium iodide is the same
stuff added to your table salt to make it iodized.
It may or may not protect your thyroid gland,
which is particularly vulnerable, from radioactive
iodine exposure. Plan to speak with your health
care provider in advance about what makes sense
for your family.
