Abstract

A quantum mechanical model of a counter monitoring the decay of an unstable microsystem is constructed. In spite of its quantum mechanical nature, the counter may be assumed to behave classically during the measurement. The relevance of this result for a particular interpretation of quantum mechanics is discussed.
