AB  - Ugalj predstavlja glavni izvor energije u Srbiji. Jedan od problema koji prati proizvodnju
energije iz uglja je problem tzv. “energetskog otpada”, kao što su leteći pepeo i šljaka, koji
predstavljaju nesagorivi i nesagoreli ostatak pri sagorevanju uglja. Leteći pepeo i šljaka
predstavljaju TENORM (Technically Enhanced Naturally Occurring Radioactive Material), a u
slučaju kada se odlažu u životnu sredinu mogu dovesti do uvećanja i/ili promene raspodele sadržaja
prirodnih radionuklida. Da bi se odredio eventualni uticaj “energetskog otpada” na životnu sredinu
analizirani su uzorci uglja, pepela i šljake iz termoelektrana “Nikola Tesla” i “Kolubara”.
U radu su prikazani rezultati koncentracije prirodnih radionuklida (uranovog i torijumovog niza,
kao i 40K) u uzorcima uglja, kao i šljake i pepela nastalih sagorevanjem uglja. Zatopljeni uzorci su
mereni nakon uspostavljanja radioaktivne ravnoteže na poluprovodničkom HPGe spektrometru
(37% relativne efikasnosti). Spektri uzoraka su snimljeni i analizirani pomoću programskog paketa
GENIE 2K, uz dodatnu analizu korišćenjem programa ANGES.
Dobijene vrednosti specifičnih aktivnosti ne odstupaju značajno u odnosu na vrednosti dostupne u
literaturi. Svi dobijeni rezultati su dodatno statistički obrađeni u cilju određivanje mogućih
korelacija.
AB  - Coal is the main energy source in Serbia. One of the problems associated with the
production of energy from coal is the so-called “energy waste”, such as fly-ash and slag (bottomash), which are incombustible and unburt residue from combustion of coal. Fly-ash and slag are
TENORM (Technically Enhanced Naturally Occurring Radioactive Material), and if they are
released into the environment an increase and/or redistribution of natural radionuclide content can
occur. To determine the potential impact of “energy waste” on the environment, samples of coal,
fly-ash, and slag from thermal power plant “Nikola Tesla” and “Kolubara” were analyzed.
The measured concentrations of natural radionuclides (uranium and thorium series and 40K) in
samples of coal as well as in slag and fly-ash produced by combustion of coal are presented in this
paper. Sealed samples were measured with a semiconductor HPGe spectrometer (37% relative
efficiency) after the radioactive equilibrium was reached. Spectra were recorded and analyzed using
software package GENIE 2K, with additional analysis performed by ANGES software.
The obtained values of specific activity do not differ significantly compared to the values available
in the literature. All the results were further statistically analyzed in order to determine the possible
correlation.
