In medical applications that involve using radioactive sources, efforts are made to ensure that irradiation does not cause any long-term effects. This is done by considering: If the half-life ...

This is done by choosing isotopes that: The half-life should be long enough to produce useful measurements but short enough for the radioactive sources to decay to safe levels soon after use.

EHSA allows for the entry of source use and waste generation by the Authorized User or Radiation Worker. This mechanism is meant to capture the dispensing of radioactive material from the original ...

The nuclei of other atoms are unstable. These nuclei undergo change spontaneously, that is, without outside help. When unstable nuclei undergo change they give off radiation. Atoms which have unstable ...
