After the Chernobyl nuclear power plant accident in April 1986, a large increase incidence of childhood thyroid cancer was reported contaminated areas. Most radiation exposure to from iodine isotopes, especially 131I. We carried out population-based case-control study Belarus and Russian Federation evaluate risk after radioactive investigate environmental host factors that may modify this risk.We studied 276 case patients with through 1998 1300 matched control subjects, all aged younger than...

After the Chernobyl accident in 1986, "liquidators" or clean-up workers were among those who received highest radiation doses to thyroid from external radiation. Some also exposed radioiodines through inhalation ingestion. A collaborative case-control study nested within cohorts of Belarusian, Russian and Baltic liquidators was conducted evaluate radiation-induced risk cancer. The included 107 cases 423 controls. Individual iodine-131 (131I) estimated for each subject. Most subjects low...
In the last three decades, an increase in thyroid cancer incidence has been observed worldwide, as well Lithuania. Although rise was linked to overdiagnosis, role of lifestyle and environmental factors, including exposure ionizing radiation, cannot be excluded. our retrospective study, we aimed assess association between average age-specific dose due radioactive iodine uptake during childhood adolescence from Chernobyl fallout Lithuania, trends 1991 2015 different regions. Averaged...
Between 1986 and 1990, several hundred thousand workers, called "liquidators" or "clean-up workers," took part in decontamination recovery activities within the 30-km zone around Chernobyl nuclear power plant Ukraine, where a major accident occurred April 1986. The liquidators were mainly exposed to external ionizing radiation levels that depended primarily on their work locations time after when was performed. Because individual doses often monitored inadequately not at all for majority of...
A population-based case-control study of thyroid cancer was carried out in contaminated regions Belarus and Russia among persons who were exposed during childhood adolescence to fallout from the Chernobyl accident. For each subject, individual doses reconstructed for following pathways exposure: (1) intake 131I via inhalation ingestion; (2) short-lived radioiodines (132I, 133I, 135I) radiotelluriums (131mTe, 132Te) (3) external dose radionuclides deposited on ground; (4) ingestion 134Cs...
ABSTRACT In this paper we analyze the radiocarbon ( 14 C) concentration changes over whole operational period of Ignalina Nuclear Power Plant (INPP) including post-shutdown decommissioning. Environmental samples from vicinity INPP and a rural area as background pine tree rings were analyzed with single stage accelerator mass spectrometer (SSAMS). The analysis shows local influence 3 to 7 pMC. time span 1983 2015 is divided into three periods representing early late stages different C...
Individual radiation doses to the thyroid were reconstructed for 2239 subjects of a case–control study cancer among young people that was carried out in regions Belarus and Russia contaminated by radioactive fallout from Chernobyl accident. Although process dose reconstruction provides point estimate each subject's dose, it is obvious there uncertainty associated with these calculations. The following main sources estimated individual identified: (1) shared unshared errors parameters...
ABSTRACT A radiocarbon ( 14 C) activity analysis in the tree rings around Ignalina nuclear power plant (INPP) has been carried out with aim to test hypothesis use C tree-ring data as a tool for reconstruction of gaseous releases from NPP environment. The INPP decommissioning state since end 2009. Tree-ring samples were collected 7 yr after final unit shutdown vicinity. 5 sampling locations collected, prepared and measured using Single Stage Accelerator Mass Spectrometer (SSAMS). Data...
The vertical distribution of radiocarbon (14C) was examined in the bottom sediment core, taken from Lake Drūkšiai, which has served as a cooling pond since 1983 for 26 years Ignalina Nuclear Power Plant (INPP) operation using two RBMK-1500 reactors (Russian acronym for"Channelized Large Reactor"). 14C specific activity measured alkali-soluble and -insoluble fractions layers. Complementary measurements 210Pb 137Cs samples provided possibility to evaluate date every layer formation, covering...
The Ignalina Nuclear Power Plant consists of two Russian-made RBMK-1500 reactors. plant uses Lake Druksiai as a natural reservoir for cooling water. Within the framework revised radiation dose limitation system, site-specific routine release conversion factors and maximum annual effective doses dominant radionuclides pathways were evaluated both atmospheric aquatic releases. Using calculated factors, locations highest predicted activity concentrations determined air dilution zone heated...
The results of an integrated study the radiocesium behaviour in Lake Tapeliai by using not only conventional data on activity concentrations lake water and sediments but also a complex set seasonal variations vertical profiles standard variables are presented.Radiocesium structure column considerably depend radiocesiumenriched inflows coloured waters from lake's swampy watershed.The global fallouts mainly responsible for inventory sediments, where maximum values found upper part above ~5.4 m...
After decommissioning of Unit 1 the Ignalina Nuclear Power Plant, problem radioactive waste management emerged. Among there is an inventory about 1700 tons graphite containing 14 C radioisotope as activation product. The estimates show that maximal total in from around 7 � 10 Bq. One possible ways for utilization its incineration processing plant. Unfortunately, this case a significant amount radionuclide would be released into atmosphere form CO2 and radiocarbon cause additional exposure...
Operation of the Ignalina Nuclear Power Plant (INPP) resulted in about 7500 tons solid radioactive waste kept 45 sections four storage facilities (No 155, 155/1, 157, 157/1) at INPP site.For safe and efficient decommissioning these storages it is important to know inventory.The nuclide vector (NV) method was used for characterization radionuclide inventory (SRW).A well planned sampling composition measurements were needed evaluate scaling factors NV.The optimal number samples N , be taken...
ABSTRACT In this study, we examined how land use and urbanization changes in adjacent areas affected biological productivity carbon cycling a lake ecosystem over 100 years these are reflected isotope variations. We performed radiocarbon ( 14 C) activity stable ratio analysis two organic fractions: humin humic acids of sediment. Additionally, pigment diatom determined the carbonate matter (OM) content sediments. Over last century, estimated C reservoir age both sediment fractions varied from...
