AD8221, RFI surveyed data for assuming how much dc offset

Hi,

We can see following description at page 20 on Rev.C datasheet of AD8221 in regard to RFI.

<in applications where there are strong RF signals. The disturbance can appear as a small dc offset voltage.>

We would like to know how much strength of RF interferences can result to how much dc offset voltage, thus if you have any data actually surveyed, or let us know any example cases, it would be very much appreciated.

Best Regards,
