Abstract
Po-214 is implanted into surfaces exposed to radon. The implantation rate c ould be sufficient to explain the rate of low-energy events with anomalousl y fast scintillation pulses that has been observed in sodium iodide crystal s used in a search for WIMP dark matter. The rate should be closely coupled in time to the radon concentration. (C) 2000 Elsevier Science B.V. All rig hts reserved.
