text: Molybdenum-99 has a half-life of 67 hours, so short-lived technetium-99m (half-life: 6 hours), which results from its decay, is being constantly produced.
text: It has the disadvantage of a long half-life (six hours), however, and other radionuclides with shorter half-lives are also used.
text: It has a short half-life (6 hours) and does not remain in the body or the environment for long.
text: The beginning of the article should address the different half-lives in the text, so that when I, the reader, see a bunch of nuke med stuff saying that the half-life is 6 hours, I won't freak when I read Industrial Technetium-99 decays almost entirely by beta decay, emitting beta particles with very consistent low energies and no accompanying gamma rays.
text: The physical half-life of technetium, Tc99m, is 6 hours and has a principal radiation emission of gamma photons with a mean energy of 140 KeV.
text: It has a short half-life (6 hours) and does not remain in the body or the environment for long.
text: 99Mo has a half-life of 67 hours, so short-lived 99mTc (half-life: 6 hours), which results from its decay, is being constantly produced.
text: The half-life of technetium-99m is 6 hours which facilitates the investigation of metabolic processes
text: That means the half life of this substance is 6 hours.
text: It has an ideal half life (six hours) which is long enough for diagnostic procedures to take place but short enough for the patient not to be inconvenienced unduly by remaining radioactive for too long a period after the investigation.
