Title Radiological
field food tester The problem the inventor(s) wanted to solve Without using the well
known slow measures methods and heavy equipment now it is possible to decide,
which nuclear radiation contaminated foods are consumable, and which are not.
It is working in field environment, does not need laboratory circumstances.
One man can carry the food tester. It has quick measure time, and can be used
without any trained staff. Description. It analyzes the spectrum of
beta and gamma radiation of all fission and activated radioactive isotopes in
same time with only one detector. It gets a lot of information about the
contamination in short time with simultaneous measurement. The base of the
process is the perception, that contamination’s have
simultaneously beta and gamma radiation and they can be divided by their
spectrum in short and long half time groups. There are four groups: low and
high-energy beta, low and high-energy gamma signals. The gamma activity of
the short and long half time isotopes in the sample can be calculated from
the spectrum groups. After the radioactive concentration of the short and
long half time groups was compared to the norm, it can be decided
automatically, if the food is consumable, not consumable, or not consumable
at the moment. Presentation. The subject of
the invention is “method, and system technology apparatus for decision
whether the contaminated food with fission and activating radioactive
isotopes is consumable or not” after a nuclear crisis, used scintillation
measure technique. The base of the
realization was the development of an intelligent scintillation detector with
a sandwich crystal, which capable to analyze the height proportionate to the
energy of impulses, and to sort by the signal weight which impulses get from
alpha, beta, gamma sensitive layers. To realize the process it
needs to separate the beta and the gamma spectrum in two-two parts, so it
will be one low one high energy beta, one just short half life time low
energy gamma, and one in first part short, in second part long half time high
energy from gamma sources channels. On that we do the radioactive
concentration calculation. With the help of content rate of two beta channels
we part the height energy gamma concentration value, we add one fraction to
the short half time isotopes, and the rest is the concentration of long half
time isotopes. We sum the beta concentration, than we compare the beta and
two gamma values to the norm, after that we calculate the consumability
with logical decisions. Application Security testing Advantages The classification is
taking place by all present (occasional 50-80), not by few presumed dominant
isotopes. The measures time decries and the reliability of the decision
increase. The size will be smaller, because the device use in place of two detector just one combined. It follows that lead shielding
of the apparatus can be decries from the normal 150 kg to 25 kg. Stage of development. The prototype is finished
in the framework of field engineer research and development, the control
tests are done. The line production can be started. Documentation available: Brochures are available in
Hungarian and English language. |
