The objective of this study was to assess the radiation exposure levels in victims of a (60)Co radiation accident using chromosome aberration analysis and the micronucleus assay. Peripheral blood samples were collected from three victims exposed to (60)Co 10 days after the accident and were used for the chromosome aberration and micronucleus.

Radiation-induced chromosome aberrations, particularly exchange-type aberrations, are thought to result from misrepair of DNA double-strand breaks. The relationship between individual pathways of break repair and aberration formation is not clear. By electrophoretic karyotyping of single-cell clones derived from irradiated cells, we have analyzed the induction of stable aberrations in haploid.

HPA-RPD doses in radiation accidents investigated by chromosomal aberration analysis XXIV: review of cases investigated, Ref: ISBN PDF, KB, 17 pages. As early as the mids, ionising radiation was known to be capable of inducing chromosome aberrations in the metaphase of human peripheral lymphocytes [1, 2].Since then, the chromosome aberration assay has been widely used as a sensitive biomarker for dose reconstruction following radiation exposure [3–6].In particular, the analysis of dicentric chromosomes and rings (dic+r), two.

The present study aims to estimate the biological doses received by five victims (A, B, C, D and E) of the Shanxi Taiyuan radiation accident in China.

titled “Biological Dosimetry: Chromosomal Aberration Analysis for Dose Assessment”, in. It is widely accepted that, in chromosome-aberration induction, the (mis-)rejoining probability of two chromosome fragments depends on their initial distance, r, several aspects of these “proximity effects” need to be clarified, also considering that they can vary with radiation quality, cell type and dose.

The analysis of chromosomal aberrations is a well-established method for assessing DNA damage in-vitro and in-vivo. Due to the solid documentation of the test in the literature, it is widely used in pre-clinical toxicology (see OECD guideline #) and as a reliable method to estimate radiation doses in unately, analysis of chromosomal rearrangements is time consuming and.

For these tasks informations such as magnitude of dose received, as external or internal radiation, or as partial or whole body irradiation are necessary.

INTRODUCTION. Chromosome aberrations are an established marker of exposure to ionizing radiation and their presence in peripheral blood lymphocytes is a widely used measure of radiation exposure ().Chromosome changes also play a major role in carcinogenesis and there is increasing evidence that their presence in peripheral blood lymphocytes provides a marker of cancer risk ().
