<unk>  is a form of radiation therapy for the treatment of cancer which relies on low-energy electrons (emitted by the<unk>  effect) to damage cancer cells, rather than the high-energy radiation used in traditional radiation therapy. Similar to other forms of radiation therapy,<unk>  relies on radiation-induced damage to cancer cells (particularly DNA damage) to arrest cell division, stop tumor growth and metastasis and kill cancerous cells. It differs from other types of radiation therapy in that electrons emitted via the<unk>  effect<unk>  electrons) are released with low kinetic energy. In contrast to traditional α- and β-particle emitters,<unk>  electron emitters exhibit low cellular toxicity during transit in blood or bone marrow. Due to their low kinetic energy, emitted<unk>  electrons travel over a very short range: way less than the size of a single cell, on the order of less than a few-hundred nanometers. This very short-range delivery of energy permits highly targeted therapies, since the radiation-emitting nuclide will be in close proximity to the delivery site (e.g. DNA strand) to cause cytotoxicity. However, this is a technical challenge;<unk> utics must enter their cell-nuclear targets to be most effective.<unk> utics are radiolabelled biomolecules, capable of entering cells of interest and binding to specific sub-cellular components. These typically carry a radioactive atom capable of emitting<unk>  electrons. The<unk>  electron emission from the atom is stimulated by radioactive decay, or by external pst (primary system therapy, e.g. x-ray) excitation.
