                        Conventional Lymphocyte Metaphase-Dicentric Assay
  • Left panel: A schematic illustrating radiation-induced DNA damage (see left side of image) in an interphase cell and the resulting formation of radiation-induced dicentric (DIC) and accompanying acentric fragment (Ac) chromosome aberration in lymphocytes arrested in metaphase mitosis.

  • Right panel: Dose response relationship for dicentrics in human lymphocytes exposed to incremental radiation doses from three radiation qualities.
