The probe DNA is labelled so that it can be detected, usually by incorporating radioactivity or tagging the molecule with a fluorescent or chromogenic dye.

Nuclear reprocessing reduces the volume of high-level waste, but by itself does not reduce radioactivity or heat generation and therefore does not eliminate the need for a geological waste repository.

The brine could leak into the repository and either dissolve radioactivity or entrain particulate matter with radioactive waste to the surface.

These two possible fusion reactions do not produce neutrons, and thus no radioactivity or nuclear waste, so they open for the first time the possibility of human-made clean aneutronic fusion.

The first indirect use of thymidine kinase in biochemical research was the identification of dividing cells by incorporation of radiolabeled thymidine and subsequent measurement of the radioactivity or autoradiography to identify the dividing cells.

Cluster decay ( also named heavy particle radioactivity or heavy ion radioactivity ) is a type of nuclear decay in which a parent atomic nucleus with A nucleons and Z protons emits a cluster of N < sub > e </ sub > neutrons and Z < sub > e </ sub > protons heavier than an alpha particle but lighter than a typical binary fission fragment ( although ternary fission into three fragments produces products which overlap cluster decay ).

ISH can also use two or more probes, labeled with radioactivity or the other non-radioactive labels, to simultaneously detect two or more transcripts.
