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. 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 a Nuclear Blast
Take cover
immediately, below ground if possible, though any
shield or shelter will help protect you from the
immediate effects of the blast and the pressure
wave.
If There is a Nuclear Blast, try to quickly assess
the situation.
Consider if you can get out of
the area or if it would be better to go inside a
building and follow your plan to "shelter-in-place."
In order to limit
the amount of radiation you are exposed to, think
about shielding, distance
and time.
SHEILDING:
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 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. Consider keeping
potassium iodide in your emergency kit; learn what
the appropriate doses are for each of your family
members. Plan to speak with
your health care provider in advance about
what makes sense for your family.
