Abstract
To evaluate the exposure of the Hungarian population to cosmic rays, the absorbed dose rate in air of cosmic radiation was directly measured by high pressure ionization chamber at ground level on the surface of different bodies of water and at various altitudes on board an aircraft. From the dose rates measured in this way, the outdoor dose equivalent rate from the ionizing components of cosmic radiation to people living at sea level would be 300–325 μSv per year. Taking into account the altitude distribution of the population, the average weighted dose equivalent is about 320, μSv per year. At Kékestetö, the highest peak of the Mátra Mountains, (the highest altitude in Hungary), the annual dose equivalent is about 50 per cent higher than on the Great Hungarian Plain.
