Abstract

First measurements of natural surface and bulk ²¹⁰Po specific activities for metals are reported. If covered with protective foils, the surfaces did not show indications of ²¹⁰Po and the obtained upper limits are in the range of single mBqm^-2. Weak bulk activities, in the range of 50 - 280mBqkg^-1, were registered for Stainless Steel and Copper, while significant amounts of ²¹⁰Po, ∼1.5Bqkg^-1, were detected in Titanium. One special Teflon sample was investigated with respect to its bulk ²¹⁰Po.
