We show how to monitor the MRI staff exposure to the $$$B_0$$$ stray-field. Monitoring is extended to several body districts without interferences with normal hospital operative procedures. The Weighted Peak index is calculated, for different Action Levels limits as from the current EU regulations, to consider the non-sinusoidal nature of exposure. Results show that exposure limits are exceeded even at 1.5 T and their occurrences significantly increase at 3.0 T scanners.
