Two workers in a nuclear medicine facility are exposed to different radiation hazards:

  • Worker 1 stands in the path of a collimated beam of γ \gamma\,γ radiation from a sealed cobalt-60 source for 5 minutes. The beam is then switched off.
  • Worker 2 accidentally inhales a small amount of dust containing a gaseous β−\beta^-β− emitting isotope.

Which option correctly describes the status of each worker immediately after these events have occurred?

Worker 1: Neither contaminated nor irradiated; Worker 2: Both contaminated and irradiated

Worker 1: Irradiated only; Worker 2: Contaminated only

Worker 1: Irradiated only; Worker 2: Both contaminated and irradiated
