radioactive

characterized by radioactivity.

radioactive decay

spontaneous decomposition of the nuclei of the atoms of radioactive substances. Measured as the proportion of the atoms in a radionuclide that decompose per unit of time, usually stated as the half-life of that particular isotope.

radioactive fallout

dissemination of radioactive substances through the atmosphere and deposition on the environment generally; causes radiation injury.

radioactive isotope

radionuclide. A radioactive nuclide, e.g. radioactive iodine or strontium.

radioactive tracer

see radioactive tracer.
