for first responders.
medical services, firefighters and public health departments may be called
upon during a nuclear emergency to map out the areas of contamination
and restrict access to the areas of higher contamination. Police and fire
departments are best served by having individual nuclear radiation detectors
in for each emergency first responder to give a timely indication of a nuclear emergency. The
durable and inexpensive Model 500 RadScanner is designed to alert you of
any increase in nuclear radiation above background levels. The silent Vibrating
Alarm built-in to the Model 500VBR is useful in high noise areas.
these simple to operate RadScanners in the hands of every first responder
is an effective technique for mapping radioactive cotamination areas. Relying upon
one or two expensive nuclear monitors will not necessarily give a good picture
of the extent of contamination.
security for concerned citizens.
ordinary citizen might have to rely upon the local health department and emergency
response teams for timely alerts of bacterial or chemical contamination from
the accidental or determined acts of others, your radiological safety is
guaranteed by the use of a RadScanner Model 500.
size, battery operated Digital Geiger counter gives you fair warning of
any nuclear radiation increases in your immediate vicinity. Local officials,
intent on preventing public panic, may delay giving you adequate warning
while they evaluate the danger and prepare an evacuation plan. This delay
may be crucial to your family's health.
increase in radiation above the background will alert you to any nuclear
contamination from a "dirty bomb" or a nuclear power plant accident. You
will be able to move quickly to move your family to safety and provide
preventative non-radioactive iodine in the form of potassium iodide tables
(KI tablets). In preparation, clean clothing and shoes can be sealed into
a plastic storage container for use when you and your loved ones are outside
the contaminated area. Carry uncontaminated drinking and washing water and
prepackaged food in your vehicle along with the sealed clothes.
Alternate Low Cost Detection Devices.
Some small "key chain"
radiation monitors are insensitive to dangerous levels of radiation. These
units are set to a trip level (0.1 rad) that is too high to protect you
and your family from dangerous levels of nuclear radiation. This is well
over the working range permitted by government regulations. This
is fifty times higher than the maximum allowed anyone working a 40 hour
week in the nuclear industry. If a disaster occurs, it is much better to
move as quickly as possible around contaminated areas and settle
in an area with a very low background. The RadScanner will find the most
habitable areas for relocation. You do not want to move your family
into an area with chronically
dangerous contamination levels not detectable by "key chain" radiation
There are a good number of old "surplus" Geiger counters manufactured
in the 1950's and 60's that are available. Some of these still work,
but do not provide an alarm function or any sort of digital total count
at environmental levels. The Geiger tubes are well aged and may not work
There are some "pen" dosimeters that are charged up with a small
power supply. The charger places an electrostatic charge on a metal coated
quartz fiber in dry gas-filled chamber. The fiber bends and is attracted
to an oppositely charged chamber wall. As charged particles speed through
the chamber they ionize a few of the molecules of dry gas which conducts
some of the charge from the bent fiber to the chamber wall. If enough ions
are formed by enough particles, the fiber straightens enough to move the
end of the fiber which points to a numbered scale. This is viewed by holding
the "pen" up to a light. These "pen" dosimeters are quite insensitive to
low levels of radiation and must be held horizontal to get an accurate reading
and avoid the effects of gravity on the fiber. The charger must
be calibrated periodically to place the same charge on each dosimeter.
Film and thermoluminescent badges require processing under laboratory
conditions to obtain results.
