Department of Radiation Research and Ecosystems Rehabilitation

The Department performs a full range of measurements of radiation parameters regulated by the applicable legislation and regulatory documents:

 

  • Monitoring the equivalent dose rate.
  • Monitoring flux density of alpha-, beta-particles.
  • Determination of radon and thoron daughter products in air.
  • Determination of radon content in water.
  • Survey of sites for building residential houses and buildings.
  • Industrial radiation control of scrap metal.
  • Assessment of solid fuel (coal) radioactivity.

  • Monitoring radiation situation when working with sources of ionizing radiation and in conditions of a radiation accident.
  • Measurement of contamination levels on working surfaces, in equipment, vehicles, personal protection equipment, on skin cover, personnel’s clothes with radioactive substances.
  • Development of protective measures aimed at reduction of the effective gamma-dose rate and radon entering premises.
  • Development of industrial radiation control system.

A pedestrian gamma-spectrometric survey allows within a short period evaluation of the content of 137Cs, 241Am, Eu isotopes, 40K, U isotopes, 60Co, 232Th, Pb isotopes in soil of areas surveyed  without soil sampling or costly analyses and identification of precise contamination borders. Survey results can be obtained after 15 minutes as radioactive contamination maps

The available equipment allow a high-precision coordinates setting afield to within 5 cm (geodetic reference to location of cable channels, identification of site turning points, setting precise drilling coordinates etc.), determination of ground elevations.
Findings can be used to create a digital relief model, 3D terrain models, drawing up topographic map-boards.

Monitoring of X-ray equipment operating parameters implies measurements of key operating parameters for X-ray diagnostic units in order to reveal non-conformity of working characteristics resulting in poorer image quality and patients overexposure. Each research is conducted using up-to-date measuring facilities and test-objects conforming to all of the technical and regulatory requirements. The laboratory controls operating parameters of medical X-ray machines of different type and purpose used in medical institutions of the Republic of Kazakhstan.

  • Monitoring of personal protection equipment.
  • Dosimetric monitoring at workplaces.
  • Estimation of radiation protection for therapy and roentgen diagnostics rooms.

Individual dosimetric monitoring is carried out for personnel working with sources of ionizing radiation in:

  • mining, oil and gas producing enterprises;
  • organizations engaged in disposal and transportation of radioactive waste;
  • enterprises that carry out radiation hazardous operations such as X-ray radiological medical rooms, civil defense and emergency subdivisions, customs and roads committees.

The inspection team for individual doses have at their disposal up-to-date equipment that allows registration of not only the effective dose but also equivalent doses received by skin and lens.
