A United States perspective on long-term management of areas contaminated with radioactive materials.

abstract：:In the present paper, the long noses of Pinocchio, Tengu and Trolls are used to measure, respectively, radon, thoron, and their decay products both by track-etch detectors and by Geiger-Müller (G-M) counters. Just recently, four new passive samplers (termed quatrefoil) have been developed which greatly simplify the de...
