Project summary

The objective of this project is to develop two devices which would emulate gamma and geomagnetic measurements and simulate the spatial anomalies of gamma and magnetic fields in the region chosen for measurements during trainings or exercises.

The first device will realistically simulate a virtual spatial gamma anomaly without any sources of radiation. Measurements with such an emulator will seem quite realistic because its appearance and interface will be very similar to that of a widely used field gamma-spectrometer. The emulator will have all necessary elements (a processor, a memory unit, software and a GPS module) to load the model gamma anomaly and to process and display its parameters corresponding to the current position in the site. A modification of the emulator for specialized measurement, e.g., detection of radio nuclides from a specified list will also be considered.

The second device will emulate geomagnetic measurements. This seems quite reasonable because the problem of simulating geomagnetic measurements during training has much in common with that of simulating gamma measurements. It is rather difficult and often impossible to use natural geomagnetic anomalies, much less to fabricate and site special magnetic sources.

Development and use of the measurement emulators for both geomagnetic and gamma anomalies will help ensure the realistic simulation of measurements for virtual anomalies of very different configurations. It will be possible to attain a high degree of realism in training in any geographical, climatic or other conditions without using expensive and potentially hazardous gamma and magnetic sources. This will help prevent damage to heath, cover all possible scenarios and in many cases reduce training costs.

The emulators to be developed will be loaded with data on model gamma and geomagnetic fields referenced to control points in the terrain or the particular site of training activities in accord with their objectives and scenario. This capability will be implemented by specific organizations which will use the emulators in their training programs. What is provided for in this project is to demonstrate capabilities of these emulators using data on one anomaly of each type.

The project will be implemented by RFNC-VNIITF workers, who are experts in nuclear physics, radiation and magnetic measurements, and computer hardware and software. Experience and knowledge they have accumulated are adequate to tasks to be resolved under the project.

The development seems to be of interest to national and international organizations dealing in

  • environmental protection,
  • monitoring of nuclear sites and facilities,
  • training of radiation emergency personnel,
  • elimination of consequences of radiation accidents or nuclear terrorism,
  • verification of international treaties in the area of nuclear nonproliferation and test ban, or
  • other activities related to gamma and magnetic measurements and personnel training.
