Kozmični žarki so visokoenergijski delci iz vesolja, ki le izjemoma prispejo do površja Zemlje, a interagirajo z jedri molekul, ki sestavljajo zrak, pri čemer nastanejo številni novi delci. Interakcija se navadno zgodi več deset kilometrov nad tlemi. Tako smo v zračnem prometu izpostavljeni kozmičnim žarkom in energijskim produktom, ki so nastali v njihovih interakcijah z jedri molekul zraka. V članku bom predstavila podatke o prejeti sevalni dozi zaradi izpostavljenosti kozmičnim žarkom za dve skupini ljudi, poklicno izpostavljenih (kozmičnemu) sevanju – letalsko osebje na komercialnih letih in astronavte. Tveganje za zdravje bo ocenjeno in podprto z rezultati študij.
Cosmic rays are high-energy particles coming from space that hardly ever hit the Earth’s surface but interact with nuclei of air molecules, usually several tens of kilometers above ground, and many new particles are formed. However, during air travel we are exposed to cosmic rays and to the energetic products of their interactions with air nuclei. In this article I will present data on the received radiation dose due to cosmic rays for two groups that are occupationally exposed to (space) radiation – commercial flights personnel and astronauts. Health risks will be estimated and backed up with study results.
