“…Thus, scientists who carried out complex radiation-hygienic monitoring in some settlements of Rokytne Raion of Rivne Oblast in 2017 confirmed that wild plants of berry plants (including cranberry) continue to make a significant contribution to annual effective doses of radiation exposure to locals (Vasylenko et al, 2018). Similar monitoring studies were conducted on the territory of the SOE "Polissya Forest Management", which is located in the western direction from the Chornobyl NPP (Chobotko et al, 2018). In general, scientists have concluded that food products of forest origin (including wild berries) make a significant contribution to obtaining an additional dose of internal irradiation (Skrkal et al, 2017), which is observed a significant increase in effective doses of internal irradiation during periods of wild berries and appearance of edible mushrooms.…”

Oligotrophic and mesotrophic bogs are common ecosystems in Polissia of Ukraine. After the Chernobyl accident, these ecosystems were contaminated with radionuclides. A common berry plant in these bogs is the cranberry, which is widely used in food industry. The aim of research is to establish dynamics of migration of 137Cs in cranberries during the last 30 years. The obtained results of monitoring studies are necessary for prognosis of radioactive contamination of cranberry. Investigation was conducted on stationary experimental plots (SEP) in Zhytomyr Polissia. 137Cs specific activity was measured on spectrum analyzers with scintillation and semiconductor detectors. Obtained results testify about intensive 137Cs migration on sphagnum bogs of Polissia of Ukraine. Results of investigation conducted after 34 years of Chornobyl accident showed low values of 137Cs specific activity in cranberry (Vaccinium oxycoccus L.) on all stationary experimental plots. This index in 2020 in fresh berries hesitate from 871±82.6 to 286±16.9 Bq/kg (at the permissible level 500 Bq/kg), and in dry shoots – from 1492 (SEP 15) to 6197 Bq/kg (SEP 12). It was found that in the first period (1991-1996) rather significant decreasing of 137Cs specific activity was observed in fresh berries of cranberry – from 3.8 times on SEP 11 to 2.2 times on SEP 12. In the next period (1996-2002) this decreasing was in the limits 1.4-2.9 times that is lower than in previous one. In the following period decreasing of 137Cs specific activity in berries was significantly lower. Revealed regularities of decreasing of 137Cs specific activity in berries during 1991-2020 also confirmed by decreasing of this index in the plant shoots. Total decreasing of this index in dry shoots on the whole period of investigation was: on SEP 11 – from 94590±4236 to 6099±366 Bq/kg (15.5 times), on SEP 12 – from 31800±2325 to 6197±242 Bq/kg (5.1 times), on SEP 15 – from 12120±898 to 1492±112 Bq/kg (8.1 times), on SEP 18 – from 14732±1126 to 1854±112 Bq/kg (7.9 times). Сontinuation of monitoring on stationary experimental plots will allow to predict levels of radioactive contamination of cranberry on the base of mathematical modeling

Screening for the 137Cs body burden owing to the Chernobyl accident in Zhytomyr region, Ukraine: 2009–2018

et al. 2021

The Chernobyl Nuclear Power Plant accident released vast amounts of various fission products, of which 131I and 137Cs are considered the most important because they are a major source of radiation exposure to the general public. 137Cs, unlike 131I, has a 30-year half-life that continues to expose people internally and externally for several decades after being deposited into the ground. 137Cs can be easily transmitted to the body through the intake of products and wild forest foodstuffs produced in contaminated areas. In the early phase, external exposure to 137Cs was predominant; however, it gradually diminished, mostly owing to horizontal and vertical distribution, and internal exposure started gaining dominance. Prior studies have shown that people in the affected areas have been constantly subjected to the inevitable low-grade internal exposure, which in turn has led to high anxiety and concern regarding the potential health effects. The present 10-year study assessed the latest status of the body burden among residents of the contaminated parts of the Zhytomyr region of Ukraine by measuring the internal concentration of 137Cs using the whole-body counter installed at the Medical Center of Korosten city. Almost 110 000 examinees from eight different districts were screened between 2009 and 2018. The study area was situated to the west of Chernobyl, which experienced a significant fallout of 137Cs and 131I from the Chernobyl Nuclear Power Plant. We analyzed the data for internal exposure to 137Cs by obtaining the actual magnitude, pace, and pattern of change for each year. During the study, the average 137Cs concentration in residents fell from 21.6 Bq/kg at the beginning of the study to 3.0 Bq/kg at the end of the study. The proportion of examinees with detectable levels had also fallen rapidly, from 45% to 11%. We found a weaker seasonal effect and a significantly higher Bq/kg concentration in adolescents than in other age groups.

The radiologically, ecologically and biologically safe mushroom raw materials are necessary to create some environmentally friendly bioorganic stimulators of plant growth and development and many other products. Therefore, we researched the population density of Ganoderma lucidum (Curt.: Fr.) P. Karst., Agaricus bisporus (J.E.Lange) Imbach, Pleurotus ostreatus (Jacq. ex Fr.) P.Kumm, Armillariella mellea (Vah1. ex Fr.) Karst., whitch are often used to create plant growth stimulants, in their natural habitat under conditions of radioactive contamination and pathogen damage. The study was conducted in six biogeocenoses: Shatsk National Natural Park (Volyn Oblast, Ukraine), Regional Landscape Park «Islands of Izmail» (Odessa Oblast, Ukraine), around the urban-type settlement of Kornyn (Zhytomyr Oblast, Ukraine), around the village of Korolivka (Zhytomyr Oblast, Ukraine), around the village of Lysivka (Zhytomyr Oblast, Ukraine), around the city of Vyshhorod (Kyiv Oblast, Ukraine). Pathogens were identified by standard mycological, bacteriological and virological methods. Radiocesium contamination density of soil, as a parameter of radioactive contamination, was determined by spectrophotometric method. The highest population density of Ganoderma lucidum was in Regional Landscape Park «Islands of Izmail». In this biogeocenosis, G. lucidum was almost not affected by pathogens, and radiocesium contamination density of soil was 18.5 kBq/m2. Agaricus bisporus and Armillariella mellea grew in biotopes with high radiocesium contamination density of soil. For example, in forest ecosystems around the city of Vyshhorod, where the average radiocesium contamination density of soil was 111.0 kBq/m2, population density of A. mellea was 0,39 fruit bodies per m2. At the same time, 15% of A. mellea in this biogeocenosis were affected by various pathogens. Thus, the use of wild mushrooms as raw materials should be preceded by testing for biological and radiological contamination.
