Keywords: Chromosomal aberrations; Biological dosimetry; Cytogenetics; Lymphocytes
Abstract: Chromosomal aberration analyses were performed in two groups of radiation workers and in a group of healthy controls. Although the level of exposure was below the accepted annual limit of 50 mSv, the yields of chromosome fragments and of total aberrations were significantly higher in the radiation workers than in the controls. However, the frequencies of dicentric and ring chromosomes in the radiation workers were not significantly different from those in the control

Keywords: Chromosome aberration; Chernobyl fallout; Radiation burden
Abstract: An investigation has been carried out to determine whether chromosome aberrations in peripheral blood lymphocytes reflect the elevated environmental dose of low-LET ionising radiation, mainly due to radiocesium from Chernobyl fallout, to the population living in Salzburg city. Sixteen volunteers were sampled 1 year after the Chernobyl accident. Two of these persons were also sampled before the accident, and then in 1988 and 1990. The radioactive environment of Salzburg city and the radiation burden of its inhabitants have been frequently determined before and after the accident. The Cs-137 content of the volunteers was measured by whole-body counting.

Title: Radiological effects on populations of Oligochaeta in the Chernobyl contaminated zone

DOI: http://dx.doi.org/10.1016/S0265-931X(02)00120-0
Keywords: Oligochaeta; The Chernobyl NPP accident; Reproduction; Chromosome aberrations
Abstract: A detailed investigation of 3 populations of Oligochaete species (Dero obtusa, Nais pseudobtusa and Nais pardalis) has been carried out in a contaminated lake of the close-in Chernobyl zone and in a control lake. Hydrochemical indices and concentrations of heavy metals, chloro-organic compounds and 90Sr in bottom sediments have been measured. Absorbed doses were calculated on the basis of the results of radiochemical analysis and assessed directly with thermoluminescent dosimeters (TLD). Stimulation of paratomous division (asexual reproduction) was found in one species of worm (D. obtusa), and activation of sexual reproduction in the two other species studied. An increase in the amount of cytogenetic damage in the somatic cells of worms from the contaminated lake was found and an attempt was made to assess the relative contributions of radiation and chemical exposure on the basis of analyses of inter-cellular aberration distributions and the types of chromosome aberrations observed in the cells.

Keywords: Bioindication; Pinus sylvestris L.; Chromosome aberrations; Chernobyl accident
Abstract: Results of a comparative analysis of the frequency and spectrum of cytogenetic anomalies are presented for reproductive (seeds) and vegetative (needles) samples taken from Scotch pine (Pinus sylvestris, L.) micropopulations growing at sites with differing levels of radioactive contamination in the Chernobyl NPP 30 km zone, and at the location of a facility for the processing and storage of radioactive wastes (the ‘Radon’ LWPE, near the town of Sosnovy Bor in the Leningrad Region). The data obtained indicate the presence of genotoxic contaminants in the environment of the tree micropopulations. Chemical toxins make the main contribution to the environmental contamination in the Sosnovy Bor area as compared with the influence of ionising radiation in the Chernobyl 30 km zone. The higher radioresistance of seeds of Scotch pine growing on the area of the ‘Radon’ LWPE and in the centre of Sosnovy Bor town was revealed with acute γ-radiation.
