Warning of gamma radiation SGI-01
|
Warning of gamma radiation GIS-01 is designed to monitor the safety of gamma-ray sources, which are placed in protective containers. Warning continuously measures the gamma radiation level at the point of its installation and generates an alarm signal in two cases: when the unauthorized extraction of the gamma source from the protective container, and in the case of unauthorized removal of the container with a source outside the alarm control zone.
An unauthorized extraction source of the container there is an increase in the radiation level at the site of the indicator unit, which leads to issue alarm indicating the alarm.
An unauthorized movement of the container with a source outside the control zone alarm level radiation is reduced, which also leads to the emission of an alarm. Warning a stationary level gamma radiation detector. Warning continuously measures the gamma radiation from the gamma block controlled source (BGI), comparisons of the measured values with the upper and lower threshold values. In the event that the level of gamma radiation is below the lower threshold or above the upper threshold, the alarm generates an alarm. The upper and lower thresholds of alarm installed by writing their values in memory signaling
Warning mounted inside a stationary location BGI comprising the radioisotope instruments Process Control -. Densitometers, gauges, thickness gauges, conveyor scales, scale-relay ... etc., or a part of medical equipment for radiotherapy
Warning detects:
a) opening of the protective container with a source of gamma radiation (BGI) - the excess of the measured gamma radiation values over threshold value;
b) absence of a source of gamma radiation (BGI) in a controlled zone - decrease of the measured values is below the threshold
