away (20
200 miles) it may arrive over a period of hours. As long as you keep the fallout dust off
of you, keep from inhaling or ingesting it, and put enough material (mass) between you and the dust to
absorb the radiation it is giving off, you will be safe. The air does not become radioactive, only the
dust and debris that falls after being thrown miles into the air by the explosion. The intensity of the
radiation given off by the dust decreases (decays) rapidly. Within 7 hours it will be one tenth of what
it was in the first hour. After two days it will be one hundredth as intense. After two weeks, it will be
one thousandth of its initial intensity.
Sheltering from the fallout radiation for a few days can easily preserve life and health. The ideal
fallout shelter would have at least a couple of feet of soil above and on all sides. However, any shelter,
even improvised, is better than none. Hunkering down for a few days in the corner of a basement can
mean the difference between life and death! The best time to evaluate shelter is before it is needed.
Identify potential shelters in your home, work or school. Stock these places with at least bottled water
and provisions for shelter improvement. To learn more about setting up an improvised and
provisioned fallout shelter, read:
WHAT TO DO IF A NUCLEAR DISASTER IS IMMINENT!
How do I know if my NukAlert
is working properly?
Your NukAlert
requires no maintenance, adjustments, connections, or battery replacement. It is
always "on". The battery sealed inside will power the instrument for over ten years at room
temperature, or somewhat less if kept at elevated temperatures. If the unit gets wet, simply dry it off
it is completely sealed. Even if water gets into the sound hole, it can
t get past the diaphragm into
the unit. The NukAlert
produces a faint ticking sound to indicate normal operation. Place the sound
hole of the device near your ear and listen for somewhat regular ticks about twice per second or
double ticks every few seconds. Either of these ticking patterns indicates a functioning unit. If your
unit is not ticking as described, or is continuously alarming in the absence of radiation, please contact
us for a replacement. The device may be tested by exposing it to x-rays (at a dentist
s office). A
single chirp alarm pattern can also be heard by subjecting the device to a sudden extreme temperature
increase (freezer to warm room). DO NOT test the instrument by nuking
it in a microwave.
Microwaves are not nuclear radiation - your unit will be instantly destroyed and the warranty voided.
