Remote radiation monitoring system



The PULSE System is designed to collect real-time information about the radiation environment from arbitrary monitoring points or from mobile objects over a Bluetooth channel.                  The system includes:

Transmitters “PULSE-1” (1 – 7 items) continuously transmitting data over a Bluetooth channel;

A computer (laptop or net book) receiving the data via the Bluetooth channel from all monitoring points within 100 metres; Software for continuous monitoring of all the transmitters, detection of disturbances and generation of sound alerts.

Each component of the system has independent power supply, which allows a rapid deployment of a monitoring network. The Bluetooth transceiver has the operating range of 100 m (Class1). Using directional antennas can extend the reception range up to 1,900 m.

The computer collects data from each transmitter separately and plots background and disturbance graphs for each. Additionally, all transmitters are monitored for the temperature, battery voltage, radio reception quality, acceleration. Security mode can be enabled if necessary, in which case any attempt to carry away the transmitter will trigger off the alarm.

All the collected data are archived. Additionally, if a surveillance cam is connected to the system, any motion detected in the monitored area will be automatically recorded and added to the archive with time stamps, which  will  simplify subsequent investigation and amplify evidence, allowing to identify the object that caused the disturbance.

Data transmitted: the power of gamma radiation, the temperature inside the dosimeter, the battery voltage and acceleration. The last parameter is very important when the security mode is enabled in order to prevent stealing the device.  Up to 7 survey meters can be connected to one computer and placed at stationary points or on mobile objects within 100m. The computer software collects data from all the meters, reflects them as graphs and saves into an archive. In other words, a radiation monitoring network can thus be deployed quickly.

The survey meter «Rhythm-7» in conjunction with external Bluetooth indicators or a PC is a ready-made solution for remote measuring.

Microprocessor-based Survey Meter «Rhythm-7» is easy to operate – all adaptation functions, setting of thresholds for alerts and measurements are automated. When connected to a PC, it is possible to transfer the historical data and adjust the microcode parameters, should the customer have special requirements.

The microcode software’s functions are as follows:

The test results of the new satellite monitoring system

for safety during transport

radiation hazardous and nuclear materials


In accordance with the “Guidelines for nuclear security related to the physical protection of nuclear materials and nuclear facilities» (INFCIRC / 225 / REVISION 5 Series IAEA nuclear security, № 13) “Transport Control Center must be fitted with equipment that provides continuous monitoring of the location of the vehicle and the state of his physical safety, as well as communication with the vehicle …”

The technology of satellite monitoring of transport is widely used throughout the world, in particular, to control traffic. In some countries, mandatory GPS Tracking Transport of Dangerous Goods enshrined in law.

The development of transport telematics technology allows, in addition to traditional data on the rate and location, transmit a lot of useful information about the status of all systems of the vehicle (acceleration, position in space, fuel level, engine temperature, etc.). Integration of radiation monitoring systems of production in modern telematics systems for the continuous monitoring of ionizing radiation at the control points on board the vehicle. All the resulting information is sent to the server of the central control and monitoring systems in online, stored in the archive, and serves as the basis for an immediate response or further analysis. Software of telematics system generates reports on transportation in both numerical and graphical form.

The prototype system «RAD-GPS» consists of a detector of gamma and beta radiation, the primary circuit conversion, high-voltage power supply, telematics GPS-controller, GSM-antenna and external GPS-antenna. The measurement data from the detecting unit to the input GPS-controller and processed together with other telemetry data and the navigation server is transmitted to the monitoring system via GPRS.

Below is a fragment of a map with the results of the first tests of the system «RAD-GPS».



To test the scenario of lost ionizing source was done on the streets of Kiev, Ukraine

Detection of gamma and beta radiation was placed on board the vehicle at a certain distance from the reference source Ra-226, whereby the count rate of 30 pcs. / sec. With a slight shift of the reference source with respect to the detector, the counting rate changes (increased to 40 pcs /sec). The fact that changes the count rate of the detector is automatically processed by the system and the center of the transport control notification. At the time 9:10:51 source “was lost” (distant from the detector). Place on the map where it happened, marked and at this point the track changes color (from red to blue). Notification in the form of SMS messages, emails, and other alarms in the center of the transport control and can come in a number of other events: deviation from the route, emergency stop, fault, alarm buttons and others. In addition, the system allows you to maintain voice and video surveillance.

Data from the telematics controller can come in encrypted form. The communication channels can be used by GSM, GPRS, 3G, or special satellite channels. Access to data from the Center of vehicle control closes with a password.

The test results of the new system of satellite monitoring of transport of radiation hazardous and nuclear materials «RAD-GPS» confirmed the high efficiency of modern technology and software to create new means of radiation control.


Radiation monitoring system “RADMON-1” – the embodiment of a new technology for decentralized radiation monitoring.

Automated Radiation Monitoring System (ARMS) are used mainly for radiation hazardous objects and represent complex hardware and software systems, which include a number of sensors (stations) that transmit data to a central location. These systems are expensive and require constant maintenance.

Development of microprocessor technology and network technologies open up entirely new opportunities for decentralized-radiation monitoring. At the turn of 2013 and 2014 by our entity was developed and tested new tools for continuous radiation monitoring with results transition for local area networks and the Internet.

Simplified algorithm of work is as the next:

  • a remote detector (scintillator or Geiger-Mueller) converts gamma radiation to an electrical signal which enters the microprocessor processing unit,
  • data processing unit performs processing of the measurement results and sends data to the Internet server,
  • data on the radiation background displayed on an interactive world map. When you click on a marker to current indications of MeV appears below the map chart of gathered data.
  • view the data on the site  can anyone who has access to the Internet.


From the user system is not required any servers or constantly-working computers! You only need to connect to the Internet. If there is no wired Internet, you can use the 3G or GPRS. All equipment is fully automatic – after the accumulating data on gamma-ray background and transmits them to the Internet. When disconnection or power-cycle power operation is restored without operator intervention.











Structurally, the device radiation monitoring “RADMON-1” consists of remote detection unit with microprocessor and power supply – (PoE adapter). The detection unit has ingress protection IP67 (to put it simply, sealed) and is set at the control of radiation background just under the open sky. Its range of operating temperatures – from minus 30 ° C to 50 ° C plus. PoE adapter is installed in the room and connect to the Internet and a network of 220 V. All the product small-sized and weighs less than 1 kg.



Gamma-vision system “Multiplex” is the newest sample of the special class of the radiation control equipment. As against dosimeters, radiometers and spectrometers “Multiplex” enables to see a picture of a radiation conditions of territory imposed to its television image on the computer screen. Thus radiating objects – both dot and extended – are allocated, the surface output from of separate objects is estimated remotely, spectra of their radiation are registered. The opportunity of remote measurement of the radiating and spectral characteristics of any site of a radiating surface of controllable territory is unique property of gamma-vision system. Moreover, all these opportunities are realized even in the event that the sources of radiation are behind a massive protection. Absence of influence of scattered gamma-radiation on results of measurements of observed sources spectra are provided by coding of a useful signal with the subsequent decoding and noise damping. The last property is very useful in a complex radiation conditions.

Areas of application:

– Monitoring of territory of dangerous radiation objects;

– Introscopic control of the state radioactive waste storehouses, containers of the ionizing radiation sources;

– Detection and remote identification of sources of gamma-radiation in emergencies;

– Detection lost, latent, disguised sources, including sources being for a massive barrier, under ground or in containers;


The “Multiplex” is realized in small-sized portable performance. In a transport situation all system is placed in two cases: in one – register with the telechamber, in other – electronic block with the computer Notebook. In a working situation the register is established on tripod with the orienting device, and the operator works with the computer, by opening the cover of the  second case.

The gamma-vision system “Multiplex” represents the device of the fifth generation of the equipment, developed and made by  Scientific Production Small Joint Enterprise “Opyt “. At development the patents for the inventions “Gamma – telescope” and “Gamma – microscope”, belonging to  SPSJE “Opyt” were used. Within the framework of this work new algorithms of digital processing of the spectral and spatial information are realized.


Results of testes:

The picture of a radiation conditions together with a television picture is saved on magnetic carriers and can be subsequently documentary. New opportunities of gamma-vision have allowed to receive unique experimental data at remote researches of inaccessible radiation objects.

This system has been tested at Chernobyl’s 10 km area. Estimation of the system was conducted in Great Britain. At a technical account British experts described the system this way: “The device Multiplex, from OPYT, has many advantages. These are its small size and high degree of portability, its ability to form images of hotspots in near real time and its use as a spectrometer. The device has the unique ability to collect spectral data from a user-definable region within the field of view. It is unknown how this is achieved and probably reflects some of the most advanced work in the field of gamma imaging.”


Place of radioactive waste disposal  – “Buriakovka.” Here is a technique that had been used in the liquidation of the Chernobyl accident. It is considered that it is not subjected to deactivation, as far as were recorded in the vicinity high levels of radiation. The gamma-ray vision “Multiplex” has been installed at a distance of 9 meters from the abandoned car. Within 5 minutes of measurements we found out that not all machine is contaminated, but only the spaces between the wheels, where radioactive soil gathered. On the combined photo and film distribution of gamma rays is indicated in the color scale. Furthermore, activity of the soil is measured remotely and is obtained its gamma radiation spectrum. Radionuclide was automatically identified. It was Cs-137.
