Biomagnetic effects: a consideration in fusion reactor development.

D D Mahlum

    Environmental Health Perspectives
    |October 1, 1977
    PubMed
    Summary

    Fusion power plants may expose workers to strong magnetic fields. Current data is insufficient to assess health risks or set safety standards for these powerful magnetic fields.

    Area of Science:

    • Nuclear Engineering
    • Biophysics
    • Occupational Health

    Background:

    • Fusion reactors require powerful magnetic fields for plasma confinement and impurity diversion.
    • These magnetic fields can extend hundreds of meters, reaching up to 450 gauss in work areas.
    • Occupational exposure to these substantial magnetic fields is a concern for fusion power plant personnel.

    Purpose of the Study:

    • To assess potential biological and health consequences of occupational magnetic field exposure in fusion power plants.
    • To evaluate the adequacy of existing literature for risk assessment and standard setting.

    Main Methods:

    • Literature review of existing studies on magnetic field interactions with biological materials.
    • Analysis of reported biological effects and their magnitude.
    • Assessment of the data's sufficiency for establishing safety standards.

    Main Results:

    • Magnetic fields can interact with biological material, but reported effects are generally small and often unconfirmed.
    • The current body of scientific literature is inadequate for a comprehensive health and environmental risk assessment.
    • Existing data is insufficient for establishing appropriate safety standards for magnetic field exposure.

    Conclusions:

    • Further research is critically needed to establish an adequate data base for assessing health risks.
    • Specific studies are outlined to provide the necessary data for setting safety standards in fusion power plants.
    • The potential health impacts of strong magnetic fields in fusion environments remain largely unquantified.
