Abstract
Zracenje iz tla ovisi o udjelu radioaktivih izotopa u tlu, a uglavnom potječe od primordijalnih nuklida uranijeva i torijeva niza (238U, 232T h) i izotopa 40K. Analizom uzoraka dobivaju se informacije o prirodnoj radioaktivnosti te učincima ljudskih aktivnosti, pri -čemu je visokorezolucijska gamaspektrometrija jedna od osnovnih metoda za jednoznačnu identifikaciju gama emitera. U radu su prikazani rezultati mjerenja koncentracije aktivnosti spomenutom metodom, a istraživanje je provedeno za šest različitih lokacija Kopačkog rita. U tlu radionuklida pronađeni su izotopi koji se često javljaju u prirodi, od kojih je očekivano najzastupljeniji 40K. Od antropogenih radionuklida zabiljezeni su izotopi cezija ( 134Cs i 137Cs) čija je prisutnost prvenstveno posljedica nesreće u černobilu i Fukushimi. 137Cs kao vanjski i unutarnji izvor zračenja od posebne je važnosti jer može predstavljati opasnost za čovjeka s obzirom na dugo vrijeme poluraspada. Najveća koncentracija 137Cs određena je na lokaciji Dunav - Kazuk i ona iznosi 22,8 Bq/kg, dok su ostale vrijednosti znatno manje.
Abstract (english)
The radiation from the soil depends on the ratio of radioactive isotopes in the soil, and mainly comes from the primordial isotopes of uranium and thorium series (238U, 232T h) and 40K. With sample analysis one obtains information about natural radioactivity and the effects of human activities, where the high-resolution gamma spectrometry is one of the basic methods for unique identification of gamma emitters. The work described in this report represents the investigation with the same method undertaken with the intention of examining activity concetrations for six different locations in Kopacki rit. Radionuclides that are generally highly abundant in the nature were detected. Along with the isotopes of uranium series the most commmon nuclide is 40K. Cesium isotopes have also been detected (134Cs and 137Cs) as a result of human activity (mainly from Chernobyl and Fukushima accident). 137Cs as external and internal source of radiation is important topic because it is highly toxic due to its long half-life of radioactive decay. The highest concentration of 137Cs is detected at Dunav - Kazuk location (22,8 Bq/kg) while the values at other locations are considerably smaller.
