    First measurements of natural surface and bulk Po specific activities for metals are reported. If covered with protective foils, the surfaces did not show indications of Po and the obtained upper limits are in the range of single mBqm . Weak bulk activities, in the range of 50 - 280mBqkg , were registered for Stainless Steel and Copper, while significant amounts of Po, ∼1.5Bqkg , were detected in Titanium. One special Teflon sample was investigated with respect to its bulk Po.
