- Abstract
Monitoring the levels of radionuclides in the environment in some areas is extremely important, not only for insight into the pollution state of the environment with radioactive substances, but also for radiation safety of the human population in a certain area. In this paper we sought to examine contamination of the National Park „Una“, located on the territory of the Municipality of Bihac, Una-Sana Canton and covers an area of 19 800 ha, by examinating the contamination of bioindicators. In 15 samples of mosses, ferns and nettles, which were collected at 5 sites in the National Park „Una“, levels of activity 137Cs were determined. Radiation load for the examined species was obtained calculating the dose rate, which provided insight into the contamination of area with radioactive isotopes. 137Cs content in plant samples at all five locations, ranged from 0.37 ± 0.10 Bq/kg to 64.60 ± 3.30 Bq/kg. Considering the literature data, it can be concluded that measured values are not significant, and measured values could not affect the radiation safety of human population in this area.
