Metrological characteristics:

  • range of kerma in the air – 7•10–9 - 3•106 Gray;
  • range of kerma rate in the air – 7•10–10 - 45 Gray/s;
  • range of photonic energy irradiation – 33 - 1250 keV;
  • value of expanded uncertainty of kerma rate measurement in the air – 2,2 - 7,0 %;
  • долговременная нестабильность за год составляет не более 0,3 %

BelGIM calibration and measurement capabilities (СМС) in the field of ionization radiation are included into Attachment С of the Agreement on mutual recognition of national standards, calibration and measurement certificates (CIPM MRA) and published on International Bureau of Weights and Measures website,

Sources of traceability:

Russia, FSUE “All-Russian Research Institute of Metrology named after D.I. Mendeleyev”, State primary standard of the units of exposure dose, exposure rate and the stream of x-ray and gamma-radiation (GET 8-82)

Scope of application:

The standard allows to carry out research, verification, calibration of devices, measuring:

  • kerma in the air; kerma rate in the air; exposure dose;
  • exposure dose rate; dose, absorbed in water;
  • dose rate, absorbed in water; equivalent dose;
  • equivalent dose rate;
  • other dose characteristics of background radiation
