Neutron monitor measurements using 10-second recording intervals were started at Oulu in September 1987. A special analysis method based on the power spectra was adopted to compensate for the relative low statistics associated with short recording in

The coincidences of cosmic-ray particles in sea-level detectors were investigated theoretically. The object of the work was to clarify the role of accompanied particles in the measurement of the spectrum of hadrons. The calculations were based on a M

The energy spectrum of cosmic-ray hadrons between 10 GeV and 10 TeV at sea level was calculated by using a Monte-Carlo method. The results show a strong steepening of the hadron spectrum at about 200 GeV. The change in the spectral slope is interpret

The energy spectra of cosmic-ray neutrons, protons, and pions were determined at sea level in the range 0.1 – 1000 GeV. The results are based on the measurements of the neutron-multiplicity distributions produced by cosmic hadrons in the Turku spec

The time structure of the ground-level event on February 16, 1984 was studied by using 30 s data of the Turku double neutron monitor. The onset time of the event was found to be (09:06:00±1) min U.T. The time between the injection of protons from th

Energy spectra of neutrons, protons and pions were measured at sea level using a cosmic-ray hadron spectrometer consisting of a double neutron monitor and scintillation counters. All the hadron spectra were determined simultaneously. The analysis of

A Monte-Carlo model has been developed for the calculation of the intensities of hadrons and muons emerging from particle cascades initiated by primary cosmic rays in the atmosphere. Special attenuation is paid to the energy spectra of the particles
