    Actinium has no biological role.
    Hazards and Risks

    Here are a few notes about the hazards and risks associated with actinium.

    Actinium does not occur to any significant extent in the biosphere and so normally never presents a risk. Actinium is studied in a few nuclear research laboratories where its high radioactivity requires special handling techniques and precautions.
