Abstract
Apparatus is provided for collecting samples of fallout, such as power plant stack emissions, from the environment. A collector substrate is adapted to progressively present a fresh collection surface for the collection of fallout from the environment over time. An opening is disposed between the substrate and the environment to allow the fallout to reach the substrate. A cover is provided for the opening. The cover is automatically closed in the presence of rain to protect the substrate from rainwater, and automatically opened after rain terminates to allow the substrate to collect fallout. Mechanical and electrical embodiments are disclosed for the automatic cover.
