Stacjonarne monitory promieniowania radioaktywnego w systemie kontroli radiologicznej

W artykule zaprezentowany zostanie rozproszony system informatyczny przeznaczony do nadzoru pracy stacjonarnych monitorów promieniowania (SMP). W artykule zostaną zaprezentowane urządzenia SMP wraz ich możliwościami i wybranymi parametrami oraz przedstawione zostaną możliwości systemu informatycznego zbudowanego do ich nadzoru. System wykorzystuje nowoczesne technologie, takie jak technologie sieciowe, kamery video IP do dokumentowania zdarzeń oraz bazy danych do przechowywania informacji.

In the paper Stationary Radiation Monitors (SRMs) and a radiology control system based on them are presented. SRMs manufactured by the division Polon of the Relpol company are described. Selected parameters of the elaborated SRM and information system to supervise their work are outlined. Components of the SRM are shown in figure 1. The basic SRM components are gamma and neutron detection modules and a control module with a touch screen and thermal printer. SRMs are used for detection of nuclear and radioactive materials. SRMs presented in the paper are a new generation of gamma and neutron radiation detector devices and can be used on border crossings, airports, nuclear factories, etc. SRMs installed in the field can be configured and monitored by a local control module or remotely by a monitoring system. The monitoring system can manage up to 16 SRMs. The monitoring system collects information about the SRM current status and events generated by the SRM and stores them in a data base. The functional and program modules and the main window view of the monitoring program are shown in figures 3 and 4. The new generation of SRMs is equipped with intelligent IP cameras with pre-triggering function. This function allows tracing a picture up to one minute before the alarm occurs. Video pictures and alarms are stored in the monitoring system data base and can be displayed by the authorized personnel.
