Keywords: Chernobyl; Radiation effect; Lymphocyte; Chromosome aberration; Automated dicentric analysis

Abstract: The frequency of chromosomal aberrations was evaluated in more than 500 liquidators of the Chernobyl accident. The ‘sarcophagus’ builders and the dosimetrists showed the highest frequency of aberrations per 100 cells: 3.24 ± 0.25 and 3.11 ± 0.43. For Chernobyl Atomic Power Station staff members the mean frequencies of aberrations per 100 cells was 2.37 ± 0.20. The mean yields of aberrations in the other groups was between 1.31 and 1.47 per 100 cells. If the mean frequencies of aberrations are converted into equivalent whole body doses, values between 136 and 414 mGy are obtained. Especially in the group of ‘sarcophagus’ builders, the yields of aberrations varied interindividually and corresponded to equivalent whole body doses of up to about 2 Gy.

Value and structure of radiation dose for emergency workers as a function of the radiation emergency mitigation phase and activity

Title: Value and structure of radiation dose for emergency workers as a function of the radiation emergency mitigation phase and activity

Keywords: Chernobyl disaster,   radionuclides,   volumetric activity,   entering organism,   liquidators,   the nature of work being performed,   137Cs content in organism,   Radiation doses,   radiation dose structure

Abstract: There was performed a research of the radiation dose size and radiation dose structure of those who participated in the elimination of the Chernobyl disaster consequences. It was established that the levels of 90Sr, 137Cs and 239Pu received by means of inhaling by the «liquidators» worked at the Chernobyl atomic power station site in June and July of 1986 did not exceed the limits set by radiation standards-76/87 of that time. The average radiation doses of the «liquidators» in 1986, 1987 and 1988 were 186, 98 and 47 mGy, respectively. The most dangerous exposure to radiation was received by those who participated in the decontamination of the third power generating unit of the Chernobyl atomic power station in June and July of 1986, their radiation doses being from 205,0±10,0 to 242,0±5,6 mGy. The body burden structure of the «liquidators» participated in the elimination in 1986 consisted of exposure radiation dose of external gamma irradiation (86 %), external beta irradiation (10 %) and internal irradiation caused by inhaling radionuclides (4 %). It was established that body burden was influenced by the following factors: the level of air and area radioactive contamination, duration of work in the contaminated areas, the nature of work being performed and personal protective equipment efficacy.

No increase in thyroid cancer among children and adolescents in Finland due to Chernobyl accident

Title: No increase in thyroid cancer among children and adolescents in Finland due to Chernobyl accident

Author: But, Anna / Kurttio, Päivi / Heinävaara, Sirpa / Auvinen, Anssi,

Reference: European Journal of Cancer, 42 (8), p.1167-1171, May 2006

doi: 10.1016/j.ejca.2006.03.006

Keywords: Radiation effects; Thyroid neoplasms; Incidence; Chernobyl; Finland

Abstract: The aim of the study was to assess whether radioactive fallout from the Chernobyl accident in 1986 influenced thyroid cancer incidence among children and adolescents in Finland. The population was divided into two: those with thyroid doses less than 0.6 mSv and above 0.6 mSv. Cumulative incidence of thyroid cancer was identified from the Finnish Cancer Registry from a population aged 0–20 years in 1986 with a total of 1,356,801 persons. No clear difference in underlying thyroid cancer incidences rates were found during the pre-Chernobyl period (1970–1985) (rate ratio RR 0.95, 95% confidence interval CI 0.81–1.10). During the post-Chernobyl period (1991–2003), thyroid cancer incidence was lower in the more exposed population than in the less exposed population (RR 0.76, 95% CI 0.59–0.98). Our results did not indicate any increase in thyroid cancer incidence related to exposure to radiation from the Chernobyl accident.

Abstract: ► We studied the effect of radiation on macroinvertebrates in Chernobyl affected lakes. ► Abundance, taxon richness, Berger-Parker dominance, Shannon–Wiener diversity evaluated. ► No relationship between community indices or abundance and radiation at up to 30 μGy h−1. ► Taxon richness varied in range 22–42: typical for uncontaminated lakes in the region. ► Natural environmental factors principal drivers of biotic assemblage structure
