ACTIONS PLAN #3 – PREVENTON OF THE UNATHORIZED APPEARANCE OF THE RADIATION SOURCE IN THE CONTROLLED AREA. PREVENTION OF THE TERRORIST ATTACKS DURING PUBLIC EVENTS

Mass events (sports, entertaining, political and other meetings) can be one of the possible places where the terrorists may use radioactive materials for the terrorist attack.

The target of the terrorists can be the spreading radiological dispersal device (RDD) or improvised nuclear device (IND) in crowded place, or for example explosion of a small dirty bomb.

The main peculiarity of this attack is that it is impossible to predict beforehand what source, in what way can be brought to the crowded place. It requires having the branchy network of the radiation detectors and prompt actions during detection of the source that also requires constant coordinating of actions of all specialists involved into control process. However, detection and search for the source is complicated due to the fact that many people are passing through the medical procedures involving treatment with various radioactive isotopes.

The POLISMART instruments can be used both independently and with the fixed-installed monitors that can be a part of the system or independently installed.

When holding the mass events the fixed-installed monitors can be installed at the entrances/exits the territory. The main task of the monitors is to give an alarm if any person passing the controlled area is having radioactive source. In the event of alarm of the monitor it is necessary to determine the reason of the alarm: whether it is medical radioactive isotope inside the human body or something else. When using the POLISMART instrument the person who is responsible for completing the radiation control procedures (for example policeman) is capable to locate and identify the source following the instructions displayed in the LCD of the instrument. If the fixed-installed monitor is a part of POLYSMART SYSTEM so since the moment it gives alarm all other procedures are filed in the DSS in real time and they can be supported online by the experts who coordinate the activity of all persons who ensure radiation control process during the mass event.

If the fixed-installed monitors are not used the numerous POLISMART instruments (PRD & Identifier or handheld identifier - RIID) will run detection process. The instruments are dispersed in the area where the mass event takes place in such so they are capable to control all possible points where the sources may appear (entrance/exit, box offices, rest rooms, etc).

The POLISMART instrument (PRD & Identifier or RIID) can be attached to the waist belt or placed into the pocket of the uniform of a policeman. It operates in automatic detection (alarm) mode. If necessary the audible alarm may be turned OFF so only vibration alarm will be enabled. In the event of alarm of the instrument the policeman must answer the following questions:

• What person may have the source


• Type of the source (medical or any other


• In case the source is medical if it is really inside the body of a person


• What actions must be taken if it is any other source


• Who must be notified in case the source is has been detected

After the instrument alarms the policeman enters its other operating modes, locate the source, measures its radiation level and completes identification. The information of the accident, with the place coordinates, time and conditions of the accident is immediately transmitted to the DMSS. If necessary the video information from the tiny video camera buikt-in in the instrument can be also sent to the DMSS. Depending on the readings of the instrument and according to the instructions displayed in the LCD of the instrument the policeman completes the necessary procedures. In case the extraordinary situation occurs when the policeman is unable to identify the source or to make a decision, he may get the support from the experts who run coordination of the actions online.

During the policeman performs the displayed procedures the information of an accident is automatically transmitted to the DMSS. This information is being processed and input into corresponding data bases. All process and procedures are supervised in the real time mode and the collected information is saved and can be obtained at any time if necessary. The information is available for the experts and persons who are responsible for performing radiation control procedures and ensuring radiation safety.
