    TEXT VERSION OF SLIDE:

    Title: Beta Particles
    Type: Text Slide
    Content:
    • High speed electron ejected from nucleus; -1 charge; light 0.00055 AMU; Typical Energy = several KeV to 5 MeV;
    • Range approx. 12'/MeV in air, a few mm in tissue;
    • Low LET (QF=1) causing light damage (6-8 ion pairs/µm in tissue);
    • Primarily an internal hazard, but high beta can be an external hazards to skin.
