Modeling the (212)Pb activity concentration in the lower atmosphere.
A worldwide radionuclide network of 80 stations, part of the International Monitoring System, is being setup to monitor compliance with the Comprehensive Nuclear-Test-Ban Treaty (CTBT). The radioactivity sampled at these stations is primarily (220)Rn progenies affecting the detection capability. A model linking the (220)Rn emanation with the sampled (212)Pb activity was developed and is presented here. The model and the performed measurements show that the variation of the sampled (212)Pb activity can be fully explained by the variation of the local (220)Rn activity concentration.
