Abstract: A cohort of 8,607 Ukrainian Chernobyl clean-up workers during 1986–1987 was formed to study cataract formation after ionizing radiation exposure. Study eligibility required the availability of sufficient exposure information to permit the reconstruction of doses to the lens of the eye. Eligible groups included civilian workers, such as those who built the “sarcophagus” over the reactor, Chernobyl Nuclear Power Plant Workers, and military reservists who were conscripted for clean-up work. Many of the official doses for workers were estimates, because only a minority wore radiation badges. For 106 military workers, electron paramagnetic resonance (EPR) measurements of extracted teeth were compared with the recorded doses as the basis to adjust the recorded γ-ray doses and provide estimates of uncertainties. Beta-particle doses to the lens were estimated with an algorithm devised to take into account the nature and location of Chernobyl work, time since the accident, and protective measures taken. A Monte Carlo routine generated 500 random estimates for each individual from the uncertainty distributions of the γ-ray dose and of the ratio of β-particle to γ-ray doses. The geometric mean of the 500 combined β-particle and γ-ray dose estimates for each individual was used in the data analyses. The median estimated lens dose for the cohort was 123 mGy, while 4.4% received >500 mGy.

Abstract: During the 25-year period subsequent to the Chernobyl accident, the morbidity of malignant renal tumors in Ukraine has increased from 4.7 to 10.7 per 100,000 of the total population. Recent studies of our group have shown that increases in morbidity, aggressiveness, and proliferative activity of renal cell carcinomas (RCCs), especially clear-cell renal cell carcinoma (CCRCC), in Ukrainian patients continuously inhabiting the radio-contaminated areas could be explained by specific molecular changes influenced by the so-called “chronic persistent low-dose ionizing radiation” (CPLDIR) exposure. This study aimed to examine the role of angiogenesis in CCRCC carcinogenesis associated with CPLDIR in patients living more than 20 years in cesium 137 (137Cs) contaminated areas after the Chernobyl accident in Ukraine. Paraffin-embedded specimens of 106 CCRCs were studied: Control cases were 18 tumors from Spanish patients (group 1), 25 tumors from Ukrainian patients from so-called clean areas without known radio-contamination (group 2), and 63 tumors from Ukrainian patients from radio-contaminated areas (group 3).

Title: Radioactive Contamination of Food in Stepanivka Village, Zhytomyr Region, Ukraine: in 1992 and in 2001
Author: Volodymyr TYKHYY
Reference: Research Reactor Institute, Kyoto University, July 2002
Keywords: contamination, food, Zhytomir region, Ukraine
Abstract: Two series of measurements of radioactive contamination in food samples were performed in 1992 and in 2001 in a village contaminated by the Chernobyl accident. The village, Stepanivka is located 120 km to the west of Chernobyl NPP and has a typical level of Cs-137 surface contamination around that area (3 – 5 Ci/km2). The study was performed by the Independent Environmental Laboratory in Kyiv, jointly founded by the Ukrainian NGO “Green World”, Greenpeace International and the International Renaissance Foundation. It is shown that the Cs-137 contamination in milk in 2001 became 9 times lower than in 1992, while the Cs-137 contamination in wild mushrooms and berries remained at the same level. Annual intake of Cs-137 by the people in Stepanivka through food products and water was about 3 times lower in 2001 than in 1992. On the contrary to the trend of Cs-137, activity of Sr-90 in milk and dried berries was significantly higher in 2001 than in 1992.

Abstract: How health messages are framed in combination with the nature of the risk (detection or prevention of disease) can impact health behavior change. Furthermore, an individual’s chronic motives and cultural values may also interact with these factors to impact the success of health message interventions. Although cultures, as well as individuals, vary in their chronic motives, rarely is research on message framing conducted outside of the United States. This is important for practical reasons (e.g., effectively responding to health threats in other corners of the globe), as well as theoretical reasons (e.g., generalized understanding of motivational/value dynamics that may moderate responses to messages).
The present dissertation examined the potentially interacting effects of cultural value priorities (i.e., value orientations such as security), personality factors (approach and avoidance motivation), and the framing (i.e., gain and loss) of the message on compliance with thyroid cancer screening messages in Ukraine. The impact of value-affirmation prior to exposure to a persuasive message on the perception of cancer risk, self-efficacy, intention, and screening behavior was also analyzed for a sample of 150 Ukrainians at risk of radiation-induced thyroid cancer due to Chernobyl fallout exposure.
Past research in the U.S. suggests that a loss-framed message might be more effective for promoting cancer detection. The pattern of findings found here instead argues that to change health behaviors both individual propensities and the nature of the message framing must be concurrently considered. , those individuals in the gain-framed, but not in the loss-framed condition, showed: (a) enhanced intent to get tested when they had both lower levels of avoidance motivational disposition and higher levels of approach disposition or valued security and (b) higher perceived self-efficacy when they valued high stimulation (an approach or gain value). On the other hand, those individuals in the loss-framed condition (compared to the gained-frame condition) showed more positive change in self-efficacy when they had low stimulation values. Additional findings are discussed. These research findings have applied implications (e.g., for targeting populations for health behaviors globally) and theoretical implications (e.g., how levels of avoid and approach motivation may combine with message framing to impact behavior change).

Keywords: Prypiat,Ukraine, Fukushima, evacuees
Abstract: This research note is a memorandum for our interviews with those who lived in Prypiat city near the Chernobyl Nuclear Power Plant. The inhabitants in Prypiat had to be evacuated to other places due to the nuclear accidents in April, 1986. We conducted the interviews with them in order to examine one of several aspects of the socioeconomic and psychological sufferings they endured. The results of our survey show that there are some remarkable damages such as loss of property and home; disintegration of labor ability, places of education and community.

Title: Cytogenetic study in lymphocytes from children exposed to ionizing radiation after the Chernobyl accident

Reference: Mutation Research/Genetic Toxicology, Volume 319, Issue 1, September 1993, Pages 55–60
DOI: http://dx.doi.org/10.1016/0165-1218(93)90030-H
Keywords: Chernobyl; Chromosome aberrations; Biological dosimetry
Abstract: The present study concerns the monitoring of children from the Byelorussian, Ukrainian and Russian republics exposed to the fall-out of the Chernobyl accident. Cytogenetic analyses have been performed on 41 children coming from different areas and exhibiting varying amounts of 137Cs internal contamination, as evaluated by whole-body counter (WBC) analysis. On a total of 28670 metaphases scored, radiation-induced chromosome damage is still present, although at a very low frequency. Due to the very low fraction of dicentrics, because of the time elapsed from the accident and the relatively low doses of exposure, radiobiological dosimetry is not possible for these children. However, considering that the WBC data indicate that the children are still exposed to 137Cs contamination, the observed occurrence of stable chromosome rearrangements and breaks may represent the persisting effect of continuous low doses of radiation. The present study also indicates that the parallel use of internal contamination dosimetry and cytogenetics could be usefully employed to monitor individual exposure to radiation and to define further management measures.

Keywords: Zhitomir, Kiev
Abstract: Dynamic models of morbidity with malignant neoplasms on four most radiocontaminated territories of Zhitomir and Kiev oblasts of the Ukraine before and after the ChNPP accident were studied as well as indices of morbidity with tumours in the former Chernobyl district in the pre-accidental period were reconstructed. At the moment of the accident 274 thousand people among them 59200 children lived in five districts. In 1993, there were 152600 people including 25700 children in four districts (without Chernobyl one). It is found that for three categories of neoplasms – solid cancers, hemoblastoses and thyroid cancer – the frequency of the latter has been reliably increased (in particular in the children age group) what can be indicative of radiation effects.
