Abstract
Alat ERICA softverski je program koji vodi korisnika kroz proces procjene, vodi evidenciju i izvodi potrebne izračune za procjenu ukupne brzine apsorbirane doze za odabrane referentne organizme. Element ocjenjivanja integriranog pristupa ERICA organiziran je u trima razinama. U ovom diplomskom radu procjenjivali smo radiološki rizik za neljudsku biotu na 8 lokacija Brodsko-posavske županije. Na razini 1 iz izbornika s popisom radionuklida odaberemo radionuklide: \( _{}^{137}\textrm{Cs}, _{}^{232}\textrm{Th}, _{}^{238}\textrm{U}, , _{}^226}\textrm{Ra},_{}^{210}\textrm{Pb}, _{}^{235}\textrm{U}\) čije su vrijednosti koncentracija prethodno izmjerene. Alat uspoređuje upisane koncentracije u tlu s najrestriktivnijim EMCL-om za svaki radionuklid i određuje kvocijent rizika (RQ). Pošto je jedan RQ > 1, prešli smo na strožu provjeru u razinu 2. Na razini 2 odabrali smo sve referentne organizme na kopnu i faktor nesigurnosti UF=3. ERICA zatim računa transfer faktore radionuklida u svakom organizmu i procjenjuje koncentracije aktivnosti pojedinih radionuklida u svakom organizmu. Razina 2 ispisala je očekivane i konzervativne RQ-ove te ukupne težinske brzine doza. Za mahovine i lišajeve je očekivani RQ < 1, a konzervativni > 1. Zbog toga se moralo dodatno istražiti o radiološkim učincima na njih.
Abstract (english)
The ERICA tool is a software program that guides the user through the assessment process, keeps records and performs the necessary calculations to estimate the total absorbed dose rate for selected reference organisms. The evaluation element of the ERICA integrated approach is organized in three levels. In this thesis, we assessed the radiological risk for nonhuman biota at 8 locations in the Brod-Posavina County. At level 1, from the menu with the list of radionuclides, select the radionuclides: \( _{}^{137}\textrm{Cs}, _{}^{232}\textrm{Th}, _{}^{238}\textrm{U}, , _{}^226}\textrm{Ra},_{}^{210}\textrm{Pb}, _{ }^{235}\textrm{U}\) whose concentration values were previously measured. The tool compares recorded soil concentrations with the most restrictive EMCL for each radionuclide and determines a risk quotient (RQ). Since one RQ>1, we moved to a stricter check in level 2. At level 2, we selected all reference organisms on land and the uncertainty factor UF=3. ERICA then calculates the transfer factors of radionuclides in each organism and estimates the activity concentrations of individual radionuclides in each organism. Level 2 printed expected and conservative RQ s and total weighted dose rates. For mosses and lichens is the expected RQ<1, and the conservative RQ>1. That is why additional research had to be done on the radiological effects on them.
