In the PGI cosmic rays laboratory, a working prototype of a portable complex for registration of secondary cosmic rays has been developed and created. The complex is designed to perform monitoring of cosmic rays in various expeditions and remote points. The complex includes detectors of neutron fluxes, charged particles and gamma radiation. The device was tested on a sea expedition in the Barents and Greenland Seas. Our task was to detect variations in gamma radiation arising in the atmosphere from cosmic rays and compare them with similar ones observed on land.
