title: Determination of the Tropospheric Residence Time of Lead-210.
abstract: The ratios of bismuth-210 to lead-210 in rain samples were used to calculate tropospheric residence time for lead-210. The value of about 6 days thus obtained agrees closely with the average interval between two rainfalls.
