AB  - A valuable tool for external quality control that provides opportunity to improve analytical skills and techniques in the field of radioactivity measurements is participation in proficiency tests (PTs). In this work obtained results from the gamma spectrometry intercomparison for 15 laboratories conducted in May 1986 immediately after the Chernobyl accident for the lucerne sample contaminated with fission products: 140 Ba, 141 Ce, 144 Ce, 134 Cs, 137 Cs, 131 I, 103 Ru, 106 Ru, 95 Zr, are evaluated following the recommendations of the international standard ISO 13528:2005. Environmental radioactivity proficiency tests organized by International Atomic Energy Agency (IAEA) are designed to identify analytical problems, to help members states to maintain their accreditation and to provide knowledge and technology transfer in this area. The Analytical Laboratories for the Measurement of Environmental Radioactivity (ALMERA) is a world-wide network of analytical laboratories capable to analyzed radioactivity contents, coordinated by IAEA. Institute for the Application of Nuclear Energy (INEP), University of Belgrade, is an official member since 2013. Annual PTs are organized by ALMERA for the network laboratories using sets of different samples. Based on the PT proposition each result should pass accuracy and precision test to be awarded the status ‘Accepted’, otherwise it lies on the status ‘Warning’ or ‘Not Accepted’. INEP was participated in three worldwide open (in 2006, 2007 and 2011) and six (in a period 2012–2016) PTs organized by IAEA and ALMERA. Radionuclide activity concentrations in different environmental matrices were measured using gamma-ray spectrometer with high purity germanium (HPGe) detector. In IAEA worldwide open PTs among 61 results, 74 % were ‘Accepted’ and 26 % were ‘Not Accepted’. In ALMERA network PTs among 70 results, 84.3 % were ‘Accepted’, 4.3 % were ‘Warning’, 11.4 % were ‘Not Accepted’. PT exercises are the best way to identify gaps and problems areas where further development is needed.

AB  - Thousands of samples of wild mushrooms from the territory of Serbia were analyzed to
determine activity concentrations of 137Cs by using gamma spectrometry in the Institute
for the Application of Nuclear Energy – INEP, during the period of thirty years after the
accident in nuclear power plant 'Lenin' in Chernobyl. Statistically analyzed results were
presented in this work. It is known that mushrooms are good bioindicators of radioactive
pollution. The level of radiocesium uptake depends on the mushrooms species, but also
of their treatment (drying, marinating, pickling). The highest activity concentration was
2390 Bq kg-1 for 137Cs (fresh weight) in 1986 in Morchella conica, while activity
concentrations 137Cs in samples collected 2015 were less than 0.1 Bq kg-1. As expected, activity concentrations of 137Cs in mushrooms decreased during the years, with some
exceptions from this trend (e.g. activity concentration of 137Cs in Boletus edulis collected
in 2002 was 1004 Bq kg-1 (dry weight)).

AB  - Tkivo lišajeva odražava elementarni sastav životne sredine, pa su oni dobri
bioindikatori i biomonitori zagađenja životne sredine, jer nemaju formiran koren,
list, stablo, kutikulu i stome, a vodu i mineralne materije upijaju celom površinom
talusa. Nivoi aktivnosti 137Cs u lišajevima BiH 1985. godine bili su od 397 do 696
Bq/kg. Srednji nivo aktivnosti 137Cs u lišajevima vrste Evernia prunastri u prvoj
polovini 1987. godine je bio 10161 Bq/kg, odnosno, 13610 Bq/kg u drugoj polovini
iste godine, a u lišajevima vrste Cetraria islandica je u drugoj polovini 1987.
godine bio 10392 Bq/kg. U periodu 1986-2015. godina, nivoi aktivnosti 137Cs u
ispitivanim uzorcima lišajeva opadaju. Srednji nivo aktivnosti 137Cs u lišajevima
vrste Hypogimnia physodes sakupljenim 2010. godine u NP Đerdap bio je 150
Bq/kg, a 2015. godine 128 Bq/kg. Nivoi aktivnosti 137Cs su u nivoima pre akcidenta
u Černobilju (1986. god), tj. novih zagađenja ovim izotopom nije bilo.
AB  - Lichen tissue reflects the elementary composition of the environment. They are
good bioindicators and biomonitors of environment pollution as they do not have
a formed root, leaves, trunk, cuticula and stoma and they absorb water and
minerals with the whole thallus surface. The activity levels of 137Cs in lichen in
BiH in 1985 were from 397 to 696 Bq/kg. The average activity level of 134+137Cs
in lichen of the Evernia prunastri species in the first half of 1987 was 10161
Bq/kg, and 13610 Bq/kg in the second half of the same year. In lichen of the
Cetraria islandicaspecies in the second half of 1987 the activity level was 10392
Bq/kg. In the period 1986-2015 the activity levels of 137Cs in investigated lichen
samples decreased. The average activity level of 137Cs in Hypogimnia
physodeslichen species collected in 2010 in NP Djerdap was 150 Bq/kg, while in
2015 it was 128 Bq/kg. Activity levels of 137Cs have dropped to levels before the
Chernobyl accident so no new pollutions with this isotope have occurred.

bioindikatori i biomonitori zagađenja životne sredine, jer nemaju formiran koren,
list, stablo, kutikulu i stome, a vodu i mineralne materije upijaju celom površinom
talusa. Nivoi aktivnosti 137Cs u lišajevima BiH 1985. godine bili su od 397 do 696
Bq/kg. Srednji nivo aktivnosti 137Cs u lišajevima vrste Evernia prunastri u prvoj
polovini 1987. godine je bio 10161 Bq/kg, odnosno, 13610 Bq/kg u drugoj polovini
iste godine, a u lišajevima vrste Cetraria islandica je u drugoj polovini 1987.
godine bio 10392 Bq/kg. U periodu 1986-2015. godina, nivoi aktivnosti 137Cs u
ispitivanim uzorcima lišajeva opadaju. Srednji nivo aktivnosti 137Cs u lišajevima
vrste Hypogimnia physodes sakupljenim 2010. godine u NP Đerdap bio je 150
Bq/kg, a 2015. godine 128 Bq/kg. Nivoi aktivnosti 137Cs su u nivoima pre akcidenta
u Černobilju (1986. god), tj. novih zagađenja ovim izotopom nije bilo., Lichen tissue reflects the elementary composition of the environment. They are
good bioindicators and biomonitors of environment pollution as they do not have
a formed root, leaves, trunk, cuticula and stoma and they absorb water and
minerals with the whole thallus surface. The activity levels of 137Cs in lichen in
BiH in 1985 were from 397 to 696 Bq/kg. The average activity level of 134+137Cs
in lichen of the Evernia prunastri species in the first half of 1987 was 10161
Bq/kg, and 13610 Bq/kg in the second half of the same year. In lichen of the
Cetraria islandicaspecies in the second half of 1987 the activity level was 10392
Bq/kg. In the period 1986-2015 the activity levels of 137Cs in investigated lichen
samples decreased. The average activity level of 137Cs in Hypogimnia
physodeslichen species collected in 2010 in NP Djerdap was 150 Bq/kg, while in
2015 it was 128 Bq/kg. Activity levels of 137Cs have dropped to levels before the

AB  - Desorption of metals K, Al, Ca, Mg, Fe, Ba, Zn, Mn, Cu and Sr from Cetraria islandica (L.) with solutions whose composition was similar to that of acid rain, was investigated. Desorption of metals from the lichen was performed by five successive desorption processes. Solution mixtures containing H2SO4, HNO3 and H2SO4-HNO3 were used for desorption. Each solution had three different pH values: 4.61, 5.15 and 5.75, so that the desorptions were performed with nine different solutions successively five times, always using the same solution volume. The investigated metals can be divided into two groups. One group was comprised of K, Ca and Mg, which were desorbed in each of the five desorption processes at all pH values used. The second group included Al, Fe, Zn, Ba, Mn and Sr; these were not desorbed in each individual desorption and not at all pH values, whereas Cu was not desorbed at all under any circumstances. Using the logarithmic dependence of the metal content as a function of the desorption number, it was found that potassium builds two types of links and is connected with weaker links in lichen. Potassium is completely desorbed, 80% in the first desorption, and then gradually in the following desorptions. Other metals are linked with one weaker link (desorption 1-38%) and with one very strong link (desorption below the metal detection limit).

AB  - Extraction of metals (K, Al, Ca, Mg, Fe, Cu, Ba, Zn, Mn and Sr) from dry Cetraria islandica (L.) Ach. lichen was performed using solutions similar to acid rain (solution A - H2SO4-HNO3-(NH4)(2)SO4 and solution B - H2SO4-HNO3-(NH4)(2)SO4-NH4NO3). The pH values of these solutions were 2.00, 2.58, 2.87, 3.28, and 3.75. Five consecutive extractions were performed with each solution. In all solutions, the extracted metal content, except Cu and Ca, was the highest in the first extract. The highest percentage of the metals desorbed in the first extraction was obtained using solutions with low pH values, 2.00, 2.58, and 2.87. The iowest percentage in the first extraction was obtained using solutions with pH 3.28 and pH 3.75, indicating influence of the H+ ion on the extraction. According to the results obtained, the investigated metals form two groups. The first group includes K, Al, Ca, Mg, and Fe. They were extracted in each of the five extractions at each of the pH values. The second group includes Ba, Zn, Mn, Cu, and Sr, which were not all extracted at each pH value. The first group yielded three types of extraction curves when the logarithms of extracted metal amounts were plotted as a function of the number of successive extractions. These effects indicate that three different positions (centres) of metal ion accumulation exist in the lichen (due to sorption, complex formation, or other processes present in the tissues).

AB  - In this paper the possibility of extracting metals: K, Al, Ca, Mg, Fe, Cu, Ba, Zn, Mn and Sr, from Cetraria islandica lichen with solutions simulating acid rain (H2SO4- HNO3-(NH4)2SO4), pH 2.00 (1) and 3.28 (2) has been investigated. The results obtained suggest that the investigated elements can be classified into ones where the highest percentage was extracted with the first extraction (K, Al, Mg, Ba, Zn and Mn) and others where the extraction percentage is relatively uniform (Ca and Fe). This indicated different bonding methods in lichen that is in accordance with literature data where two cation bonding methods in lichen were shown.
