摘要：

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