Nuclear Physics Institute of the CAS, public research institution, conducts research in a broad field of nuclear physics, experimental as well as theoretical.

Competences and capabilities

Research related to space focuses mainly on simulation and measurements of cosmic radiation at high-mountain observatories, onboard aircraft, spacecraft, and satellites, application and development of active and passive detectors, radiation protection, individual monitoring of aircraft crew.

The largest experimental facilities of NPI are cyclotrons U-120M and TR-24, electrostatic accelerator Tandetron TN 4130MC, cyclic electron accelerator microtron MT25, and 300 kV accelerator mass spectrometer MILEA.


NPI provides services using beams of gamma rays and charged particles, including irradiation services for the subsidiary company RadioMedic Ltd. (production of radiopharmaceuticals), calibrations of dosimetry systems for radiotherapy hospital departments, dosimetry audits of therapeutic irradiation systems, calculations of level of irradiation for aircraft crews, radiocarbon dating of samples, monitoring activities of 14CO2 and 85Kr in the air.
