Tom K. Hei Ph.DEditorial - What is the relevant target?
By Tom K. Hei Ph.D

For over a century since the discovery of X-rays by the German physicist Conrad Röntgen, it has always been accepted that the deleterious effects of ionizing radiation such as mutation and carcinogenesis are due mainly to direct damage to DNA. As such, generations of students in radiological sciences have been taught that such heritable biological effects are the consequence of a direct radiation-nuclear interaction. With the advances in microbeam technology and the unequivocal demonstration that targeted cytoplasmic irradiation results in mutations in the nuclei of hit cells, the concept of extranuclear target of ionizing radiation has since been firmly established. Using a charged particle microbeam, there is clear evidence that cells that are NOT directly traversed by a particle, but in the vicinity of one that is, or having received signals from such cells, can participate in the damage response.
