Description. This manual is a revision of Technical Reports Series No. , Biological Dosimetry: Chromosomal Aberation Analysis for Dose Assessment (). It provides the latest information on standardized conventional methods used for the cytogenetic assessment of doses incurred through ionizing radiation (scoring dicentric chromosomes) and on newly . Cytogenetic analysis of peripheral blood lymphocytes is the most sensitive and reliable method currently available for in vivo assessment of the biological effects of exposure to radiation and. · Applying the method first proposed by Dolphin and mentioned in the IAEA manual on cytogenetic analysis for radiation dose assessment, the overdispersion found in the dicentrics data in the first blood sample () suggests that .
Cytogenetic damage is then assessed by experts and dose assessment is made by comparison with an ap-propriate calibration curve, taking into consideration radiation type, dose rate, whole- or partial-body exposures, delay between samplings, and specific cytogenetic assessment.5 Biological dosimetry is the measurement of radi-. Cytogenetics is the gold-standard in biological dosimetry for assessing a received dose of ionizing radiation. More modern techniques have recently emerged, but none are as specific as cytogenetic approaches, particularly the dicentric assay. Here, we will focus on the principal cytogenetic techniques used for biological dosimetry: the dicentric assay in metaphase cells, the micronuclei assay in binucleated cells, and the premature condensed chromosome (PCC) assay in interphase cells. Cytogenetic analysis was applied to eight patients, all treated for the same tumour localisation; the same localisation was used to prevent the variability usually observed between patients treated with radiotherapy and to allow the corresponding roles of the size of irradiation field and of the dose rate to be studied.
