Decontamination effectiveness of ammonium-ferric(III)-hexacyanoferrate(II) (AFCF) in reducing the radiocaesium transfer to hen eggs was examined. The albumen activity concentration for ¹³⁷Cs was higher than that in egg yolk. The most effective reduction of radioactivity concentrations in all egg components was noted in birds treated with hexacyanoferrate from the first day of radioisotope administration. Radioactivity concentrations in hens treated simultaneously with ¹³⁷CsCI and a caesium binder were lower by >90% than those in the controls at selected measurement intervals. The decontamination efficiency lowered with the delayed AFCF treatment.

Mobile forms of radionuclide 137Cs in different soils (natural pastures) of northeastern Poland were evaluated. An attempt was made to show if and what mobile forms of 137Cs are related to different soil properties. For this reason 108 soil samples from 0 to 10 cm in depth were measured for mobile forms of 137Cs activity and analyzed for clay fraction, pH-value, exchangeable potassium (Kex.), exchangeable calcium (Caex.), magnesium (Mgex.), sodium (Naex.) content, organic matter and organic carbon content (C org.), and cation exchange capacity (CEC). Samples of soils were collected in the period from June 1995 to July 1996. The radiocaesium and mobile forms of 137Cs activity were determined by gamma spectrometry. The mobility of 137Cs was studied by means of sequential extraction. Mobile forms of radionuclide l37Cs were related to physicochemical parameters of soils.

Current levels of radiocaesium in game were determined. Samples were taken in 10 regions and measured for their ¹³⁷Cs and ¹³⁴Cs activity concentrations. ¹³⁷Cs was found at measurable levels in the samples analysed. ¹³⁴Cs activity concentrations were negligible (below minimum detectable activity - MDA). The ¹³⁷Cs activity concentrations were very variable between and among the animal species even in the same region and ranged from MDA values to some tens of Bq/kg. An effective dose received by the most exposed populations was assessed.

The transfer of radionuclide l37Cs from uncultivated different soils (natural pastures) to grass in northeastern Poland was evaluated. Samples of soil and grass were collected from the same area of about 1 m2 in the period from June 1994 to July 1995 twice a year. Grass was sampled from 1 m x 1 m squares by cutting to the plant base. The 137 Cs and 40K activity concentrations were determined by gamma spectrometry. The average concentration of 137Cs (to 10 cm depth) in the studied soils ranged from 17.94 Bq/kg to 37.78 Bq/kg dry weight. The average concentration of radiocesium in grass varied from 1.03 Bq/kg to 12.33 Bq/kg dry weight and depended upon the type of soil.

This paper presents the results of a study on the 137Cs content in liver, kidneys and biceps muscles of red deer (Ceravus elaphus) obtained in Warmia and Mazury in 2000/2001. 93 samples from 51 red deer shot in the communes of Reszel, Lelkowo, Olecko, Kętrzyn, Pisz, Ruciane Nida, Ryn, Szczytno, Orzysz, Rozogi, and Olsztynek were analyzed. Concentrations of radiocesium in several samples of muscle tissue of red deer obtained from the European part of Russia was determined for reference. In Warmia and Mazury the average concentrations of 137Cs were 20.48 Bq/kg in muscle, 13.26 Bq/kg in liver, and 18.74 Bq/kg in kidneys. As such, these were very low figures. It was only in a few samples of red deer tissues obtained at two locations (Olsztynek, Zaporowo) that the levels of this radionuclide were elevated compared to those from other sites. The least radioactive were samples collected from carcasses of calves, in contrast to those taken from bucks, which contained the highest levels of radiocesium. A wide range of differences in the determinations was obtained. For example, concentrations of radiocesium in muscle tissues varied from 1.91 to 28.55 Bq/kg for calves, 0.91 to 79.20 for does and 2.69 to 137.20 Bq/kg for bulls. The 137Cs levels in red deer’s potential foodstuffs also varied from region to region, although it was to a certain extent positively correlated with the amounts of radiocesium determined in the red deer carcasses obtained in these areas.

nr 1

The decontamination efficiency of ammonium ferric hexacyanoferrate (AFCF) in lowering the radiocaesium transfer to muscles and inner edible organs of broiler chickens was examined. The highest decontamination effectiveness was noticed in the birds treated with AFCF from the first day of radionuclide administration. Generally, the radioactivity levels in the animals treated simultaneously with ¹³⁷CsCI and a caesium binder were by >80% lower than those in the control ones. The decontamination efficacy lowered with the delayed AFCF treatment. lt seems thai this compound is the most suitable decontamination agent for chickens because of its efficiency, simple way of application, and a very low quantity needed for effective decreasing Cs-137 tissue contents. Moreover, ammonium ferric hexacyanoferrate presents no toxicological hazard for food producing animals and consumers.

The main 137Cs accumulation zone in the study area was found to be located at depths below the 50-metre isobath, i.e. below the layer of hydrodynamic activity. In coastal waters not influenced by the fresh water discharge from the Curonian Lagoon, 137Cs occurs mostly in soluble form. The particulate 137Cs activity concentration in the marine area affected by Curonian Lagoon water can make up 10% of the total 137Cs activity concentration. The circulation model was developed to assess the distribution of artificial radionuclides in Lithuanian territorial waters. The model was validated on the basis of data acquired during the measurement campaign in the Lithuanian part of the Baltic Sea and the Curonian Lagoon in the years 1999–2001. The model enables the 137Cs activity concentration to be simulated as a passive admixture (error within c. 15%).

Decontamination effectiveness of ammonium-ferric(lll)-hexacyanoferrate(II) (AFCF) in reducing the radiocaesium transfer into dairy goat milk was examined. The most effective reduction of radioactivity burden in milk was found in animals treated with AFCF as early as the first day of radionuclide contamination. Milk radioactivity concentrations in goats treated simultaneously with ¹³⁷CsCI and hexacyanoferrate were over 10-fold lower than those in the controls at all measurement time points. Decontamination efficiency was reduced when AFCF treatment was delayed.

The decontamination effectiveness of bentonite from Polish geological deposits in reducing the radiocaesium transfer to hen eggs was examined. The egg white radiocaesium concentration was higher than that in egg yolk. The highest decontamination efficacy in all egg components was noticed in animals treated with bentonite from the first day of radionuclide administration. Generally, the radioactivity concentration in hens treated simultaneously with ¹³⁷CsCI and a caesium binder were lower by >50% than those in the controls. The decontamination efficiency lowered with the delayed bentonite treatment. In Poland bentonite seems to be an alternative to other decontamination agents.

This paper encloses results of field tests carried out on two types of organic soils. Activities of caesium, originating from global fallout as well as from the Chernobyl power plant breakdown, were measured for these two soils. Radioactive caesium is present to a depth of 40 and 70 cm, in black soil and in peat, respectively, although the highest activity was found in the topmost layers. Caesium originating from the Chernobyl accident constitutes about 70% of the total activity in the 0-10 cm layers of the soils. The vertical migration rates of caesium from both sources were also measured. In the case of peat soil the migration rate of the Chernobyl caesium as well as that from global fallout were found to be similar and amounted to 0.2 cm/year. In the case of black soil the differences were more pronounced (0.34 and 0.14 cm/year, respectively). Results of the physicochemical analysis of both tested soils are also included in this work.
