ACTIONS PLAN #2 – PREVENTING THE ILLICIT
APPEARANCE OF THE RADIATION SOURCE IN THE CONTROLLED AREA.
DETECTION OF THE SOURCE WHEN CHECKING THE VEHICLES ON THE
ROAD WITHINTHE SCOPE OF PREVENTING ACTIONS AGAINST RADIATION
AND NUCLEAR TERRORISM.
The POLYSMART PRD & Identifier or hand-held multipurpose
identifier can be attached to the waist belt or can be placed
into the pocket of the uniform of the traffic police officer
and it operates in the automatic detection (alarm) mode. If
necessary the audible alarm can be turned OFF and the instrument
will operate only with the vibration alarm. During inspection
of the vehicle (checking the documents, inspection of the
cargo if necessary, etc) depending on the type of the detector
the instrument is capable to detect even the least deviations
of radiation background from the natural one that means that
the radioactive source is present in vehicle.
In this situation the inspector must answer the following questions:
- Location of the source
- To what extent it is harmful from the point of view of radiation
risk
- Type of the source (natural or artificial)
- If the source is artificial what origin it is
- What actions must be taken
- Who must be informed that the source has been detected
The inspector is capable to answer all these questions using
the hand-held multipurpose instrument, incorporated in the
POLISMART system.
After alarm of the instrument the inspector enters its other
operating modes, locates the source, measures its radiation
level and identifies the source. The place coordinates are
automatically tied-in and the information of the accident,
place, time and conditions of the accident is immediately
transmitted to the DMSS. If necessary the information can
be transmitted to DMSS from the video camera built-in in the
instrument (license plate of the vehicle, picture of the driver,
etc). Depending on the readings of the instrument the inspector
performs the following actions based on the instructions displayed
in the LCD of the instrument:
- If the source is identified as the natural one and its
radiation level does not exceed the allowable limits, the
inspector lets the vehicle pass. The allowable values of
the radiation levels of natural radionuclides are saved
in the memory of the instrument or they can be obtained
by sending request to the DMSS
- If the instrument detects the radiation source in the
body of the driver and the driver has document confirming
use of pharmaceutical medication and the instrument identifies
the presence of medical isotopes, the inspector lets the
vehicle pass
- In case the source is artificial, its type is determined
and it corresponds to the information declared in the shipping
documents (legal transportation), the inspector lets the
vehicle pass. The confirmation that this transportation
is legal can be also obtained from the DMSS which data base
contains the corresponding information provided by the sender
of the cargo or by customs service if the cargo is delivered
from a foreign country
- In case it is proved that the illicit trafficking of the
artificial source takes place, so depending on the type
of the source, its radiation level, etc the inspector contacts
online the corresponding service or organization. After
the inspector completes all necessary procedures the information
where and who the inspector should contact is displayed
in the LCD of the instrument
When the inspector performs all specified procedures the information
of the accident is automatically transmitted to the DMSS systems.
This information is processed and input into corresponding
data bases. All processes and procedures are supervised in
real time mode and the collected information are saved and
obtained any time if such necessity occurs.
The information is available for the experts and persons
responsible for performing the radiation control procedures
and ensuring radiation safety.
NOTE: From the experience, in most of the cases,
especially during checking of the trucks the multiple alarms
of the instrument are caused by “innocent sources” i.e. by
natural radionuclides. Due to this reason the possibility
of performing fast identification of these alarms in the field
conditions is very important. Especially if to take into consideration
the fact, that in the event of smuggling of the source the
criminals will try to hide them in the cargoes with the high
concentration of the natural radionuclides. Using the POLISMART™
system gives a real possibility to solve this problem for
the first time in the world. |
