Description:
Inventories of fallout ^2^1^0Pb and ^1^3^7Cs have been measured in moorland and woodland soils around the Edinburgh urban area, using a high purity germanium detector. The ^2^1^0Pb inventories in moorland soils were relatively uniform, with a mean value of 2520+/-270Bqm^-^2. The mean ^1^3^7Cs inventory in moorland soils varied greatly from 1310 to 2100Bqm^-^2, with a mean value of 1580+/-310Bqm^-^2. The variability was ascribed mainly to the non-uniform distribution of fallout Chernobyl ^1^3^7Cs. The mean ^2^1^0Pb and ^1^3^7Cs inventories in woodland canopy soils were found to be 3630+/-380Bqm^-^2 and 2510+/-510Bqm^-^2, respectively. At sites for which both moorland and woodland data were available, the mean inventories provided fairly similar average enhancements of (47+/-7)% and (46+/-18)% of ^2^1^0Pb and ^1^3^7Cs under woodland canopy soils relative to open grassland soils, respectively. The enhancement factors are broadly in line with other independent findings in literature. Enhancement of both ^2^1^0Pb and ^1^3^7Cs in woodland soils relative to moorland soils is, in part, due to deposition by impaction during air turbulence, wash-off, gravitational settling and deposition during leaf senescence. Results of this study suggest that these processes affect both ^2^1^0Pb and ^1^3^7Cs carrier aerosols in a similar way.
