“In essence, the process involves binding a radioisotope to a compound that has a specific affinity for an organ or region of the body.”

“Even a seemingly tiny piece of radioisotope like plutonium can be emitting many millions of alpha, beta or gamma particles per week.”

“The region of the lesion is injected with a blue dye and radioisotope tracer.”

“In addition, a number of radioisotopes, both natural and man-made, have been identified as beta emitters.”

“Other radioisotopes are produced in fission reactors through bombardment by the neutrons that were released in the fission chain reaction.”

“Neutron activation analysis is a method of producing radioisotopes in very small samples of a material.”
