چکیده انگلیسی
Polyethylene and copper samples were exposed to the underground air at SNOLAB for approximately three months while several environmental factors were monitored. Predictions of the radon-daughter plate-out rate are compared to the resulting surface activities, obtained from high-sensitivity measurements of alpha emissivity using the XIA UltraLo-1800 spectrometer at Southern Methodist University. From these measurements, we determine an average 210Pb plate-out rate of 249 and 423 atoms/day/cm2 for polyethylene and copper, respectively, when exposed to radon activity concentration of 135 Bq/m3 at SNOLAB. A time-dependent model of alpha activity is discussed for these materials placed in similar environmental conditions.
