Mains (50 Hz) pickup in .SQUID magnetometers used for l~'omagnetic measurements on the human body is a well known problem, particularly when the SQUID is used in an unshielded environment\_ We describe a simple phase-zensitive detector system which will suppress this undesirable 50 Hz signal by up t
