title: [Enhancement of the biological effectiveness of low-energy quantum radiation. Microdosimetric basis for a selective radiation effect on chromosome material in cells].
abstract: Microdosimetric data are presented indicating the possibility of a selective action of ionizing radiation on the chromosomal material of cells using low-energy electrons and photoelectrons formed, as the result of the photoeffect, on the incorporated or native atoms inside DNA upon irradiation with low-energy quantum radiation ("X-activating" effect). A presumed biological effectiveness of the "X-activating" effect on B-16 melanocarcinoma, with bromine and iodine incorporated into the DNA molecule, was estimated.
