Distributed network of the posts of radiation control and radiation and ecological monitoring "REGION".
|
The system "REGION" consists of a number of distributed posts for collecting the radiation information and a central post which gets the information from them. The distributed posts send the information on the telephone lines and with the help of GSM-canal (mobile connection). The quantity of posts is not limited. - they can be installed in every place where there are electricity and telephone or mobile communication. There can exist more than one central post, it can be stationary or mobile.
ÑThe network of the posts "REGION" functions absolutely automatically. Remote posts measure the capacity of doze and spectrum of gamma-radiation, solidity of flux of beta-radiation, react to the neuron radiation day and night. All the received information is saved in the energy independent memory of the remote post. The central post periodically sends an inquiry from the remote posts, collects the accumulated information and saves it in the archive. When the radiation anomaly which exceeds the level of reaction of the remote post appears, it immediately switch on the signal system and sends a message to the central post. Besides, when the radiation danger is high the remote post calls up the responsible for the situation people and with the help of a synthesized voice reports the level of capacity of gamma-radiation and the time when the anomaly appeared.
On the base of the received spectrum of gamma-radiation from the remote post, the operator of the central post has the ability to identify the appeared radionuclids and make a conclusion about their origin (natural or technogenic).
Technical characteristics:
• The range of registered energy of gamma-quanta, MeV - 0.05... 3.0;
• The relative energy resolution on gamma-line 137Cs(662 keV) - no more 9 %;
• The range of measuring capacity of the equivalent doze of gamma-radiation - from 0,01 mkSv/h to 2mkSv/h .
• The main relative error while measuring the capacity of the equivalent doze of gamma-radiation - no more 15 %.
• Instability of the readings - ±5 % - on the whole range of temperature from -30oÑ to +50oÑ.
• Time of uninterrupted work from the reserve supplying - no less 24 h.
In 2003 the posts of radiation control "REGION" passed the State metrological certification.
