AB  - U radu se razmatraju brzine brojanja fonskih, dvostrukih i trostrukih, koincidencija kod
spektrometra PRIPJAT, sa šest NaI(Tl) detektora, geometrijom mjerenja ~0.7x4p sr i
vremenom rezolucije koincidencija 40 ns. Analizovane su i diskutovane dvostruke i
trostruke koincidencije u energetskom opsegu (200-3000) keV, u cijelom dijapazonu i u
energetskim prozorima koji odgovaraju oblastima fotopikova gama zraka, koji se u
fotopiku registruju samo u integralnom i nekoincidentnom režimu rada spektrometra.
Razmatrani su zraci energija 662 keV (deekscitacija 137Ba nakon b
-
-raspada 137Cs), 911
keV (deekscitacija 228Th pri b
-
-raspadu 228Ac, u nizu 232Th) i 1461 keV (deekscitacija
40Ar pri raspadu 40K). Brzine brojanja u fonskom spektru, kao i brzine brojanja u
spektrima 137Cs, 232Th i 40K nakon oduzimanja fona raspoloživim kombinacijama
parova (uglovi ~90° i ~180°) i trojki detektora koje mogu registrovati dvostruke i
trostruke koincidencije, pokazale su da glavni doprinos fonskim dvostrukim koincidencijama daju fotoni rasijani iz kristala u kristal.
AB  - The counting rates of the background double and triple coincidences at the PRIPYAT
spectrometer, with six NaI(Tl) detectors, registration geometry ~0.7x4 sr, and time
resolution for coincidences 40 ns, are considered in the work. Double and triple
coincidences in the energy range (200-3000) keV, in the whole region and in the energy
windows corresponding to the photo-peaks of gamma rays, which are registered in the
photo-peaks in the spectrometer integral and non-coincidence mode of counting only,
have been analyzed and discussed. Considered rays were ones with the energy 662 keV
(de-excitation of 137Ba, after b
-
-decay of 137Cs), 911 keV (de-excitation of 228Th,
b
-
-decay of 228Ac, in the 232Th series) and 1461 keV (de-excitation of 40Ar, decay of 40K).
Counting rates in the background spectrum, as well as in the spectra of 137Cs, 232Th and
40K after background subtraction, obtained by the detector duplets (angles ~90° and
~180°) and triplets of detectors capable to register double and three-fold gamma
coincidences, showed that the main contribution to the background double coincidences
was given by the photons scattered from crystal to crystal.

AB  - Mjerenja koncentracija aktivnosti 239+240Pu i 238Pu u uzorcima zemljišta iz Crne
Gore vršena su u Minsku (BelGIM) i u Helsinkiju (STUK), utvrđeni su njihovi
međusobni odnosi, kao i odnosi koncentracija plutonijumovih izotopa i 137Cs. Na
osnovu toga je diskutovano i njihovo porijeklo, a na osnovu aktivnosti 137Cs
izmjerenih na teritoriji Crne Gore na 91 lokaciji (67 – samo površinski sloj, 24 –
slojevi: 0-5 cm, 5-10 cm i 10-15 cm) procijenjeni su i u ovom radu predstavljeni
nivoi aktivnosti Pu izotopa.
AB  - The measurements of 239+240Pu and 238Pu activity concentration in soil samples
from Montenegro, together with 137Cs activity measurements in the same samples,
were used to determine the activity ratios enabling a discussion about origin of
these radionuclides, as well as estimating Pu isotopes level in soils at the territory
of Montenegro. The 239+240Pu/137Cs activity ratio was found to be with an average
of 0.020 and standard deviation of 0.007, the 238Pu/137Cs – with an average of
0.0006 and standard deviation of 0.0003, the 238Pu/239+240Pu – with an average of
0.030 and standard deviation of 0.007, confirming that plutonium isotopes, today
present at the territory of Montenegro, originated from the global fallout. These,
as well as the other results showed that 137Cs today present at the territory of
Montenegro predominantly has the Chernobyl’s origin. Based on 137Cs activity
concentrations in the Montenegro soils measured in the period 1994-2011, using
in situ and standard laboratory HPGe spectrometric method, levels of soil
contamination with plutonium isotopes have been evaluated and discussed – for
91 locations (67 – surface soil only, 24 – layers: (0-5) cm, (5-10) cm and (10-15)
cm). The highest measured 137Cs activity in top soils in 1994 was 740 Bq/kg, in
2001 – 1710 Bq/kg, in 2002 – 2011 Bq/kg, in 2011 – 413 Bq/kg, while the highest
estimated (and measured) 239+240Pu in 2011 – 8.3 Bq/kg.
