    EDITOR,--The Danish1 and Finnish2 studies suffered from similar serious shortcomings to those which have plagued much of the published research on the possible adverse health effects of power-frequency magnetic fields.

    Firstly, as part of their objective both studies only considered high voltage ( > 50 kV and > 110 kV) power lines. The effect of this is to greatly reduce the likelihood of any associations being found, because many cases will occur in equally high magnetic fields due to other sources, and the …
