abstract = "The study was aimed at assessing the human health risk potentially induced by the presence of natural
radionuclides and their decay chain daughters in the soil of the area impacted by coal combustion in the
largest Serbian coal-based thermoelectric power plant “Nikola Tesla A”. The total intakes of 40K, 226Ra
and 232Th for residents in the study area through ingestion and inhalation of soil particles, ingestion of
fruits and vegetables, as well as external irradiation, were evaluated, and the derived carcinogenic risk
was characterized applying methodology of the US EPA based on minimal, median and maximal values
of specific activities of mentioned radionuclides in soil measured by gamma-ray spectroscopy. The total
excess lifetime cancer risk was in the range (1.70–3.91) × 10-4, which is higher than the established
target value of 10-4. Ingestion of homegrown produce was identified as an exposure route of the most
concern, followed by external irradiation originating from radionuclides investigated. The risk posed by
inhalation of soil particles found to be negligible, while direct ingestion of soil resulted with total risk
slightly above the US EPA screening level of 10-6. The results of the study will contribute to a better
understanding of the radiation hazard coming from natural radioactivity in the Serbian region that is
most affected by operation of coal-fired thermoelectric power plant., Cilj istraživanja je procena rizika po zdravlje ljudi usled prisustva prirodnih radionuklida i njihovih
potomaka u zemljištu na prostoru koji je pod uticajem sagorevanja uglja u najvećoj termoelektrani u
Srbiji „Nikola Tesla A“. Procenjeni su ukupni unosi 40K, 226Ra i 232Th za stanovnike istraživanog prostora
usled ingestije i inhalacije zemljišta, ingestije voća i povrća gajenog na istraživanom prostoru i spoljnjeg
izlaganja jonizujućim zračenjima. Procena rizika od kancerogeneze tokom životnog veka je izvršena
koristeći metodologiju Agencije za zaštitu životne sredine SAD (US EPA), polazeći od minimalnih,
maksimalnih i vrednosti medijane za specifične aktivnosti analiziranih radionuklida čije su specifične
aktivnosti određene spektrometrijom gama zračenja. Ukupni rizik od kancerogeneze tokom životnog
veka je bio u opsegu (1.70–3.91) × 10-4 što premašuje gornju graničnu vrednosti rizika od 10-4 prema
US EPA. Ingestija voća i povrća gajenih na istraživanom prostoru je identifikovana kao put izlaganja sa
najvećim rizikom, a sledi ga spoljašnje ozračivanje od stane analiziranih radionuklida. Rizik izazvan
inhalacijom zemljišnih čestica je bio zanemarljiv, dok je procenjeni rizik usled direktne ingestije zemljišta
iznosio nešto više od 10-6, što je donja granica tolerantnog rizika prema US EPA. Rezultati istraživanja
doprinose boljem razumevanju radiološkog rizika koji potiče od prirodne radioaktivnosti u regionu Srbije
koji je najugroženiji radom termoelektrana na ugalj.",
