摘要：

Po-214 is implanted into surfaces exposed to radon. The implantation rate could be sufficient to explain the rate of low-energy events with anomalously fast scintillation pulses that has been observed in sodium iodide crystals 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 rights reserved.
