from ICRP Publication 131, 2015

A mode of cell death in which the cell nucleus displays characteristic densely staining globules, and at least some of the deoxyribonucleic acid (DNA) is subsequently broken down into internucleosomal units. Sometimes postulated to be a ‘programmed’ and therefore potentially controllable process.

from ICRP Publication 118, 2012

A mode of rapid cell death after irradiation in which the cell nucleus displays characteristic densely staining globules, and at least some of the DNA is subsequently broken down into internucleosomal units. Sometimes postulated to be a ‘programmed’ and therefore potentially controllable process.
