Activities of 210Pb carrier aerosols in an age-graded Sitka spruce conifer, three deciduous (oak, lime and sycamore) foliage and in rain and throughfall samples have been measured during the period of 2001–2002. The 210Pb ...

rchard experiments were carried out in Botswana with the objective of evaluating the effect of 2,4- dichlorophenoxyacetic acid (2,4-D) on reducing premature fruit drop. Different concentration levels of the 2,4-D (8, 16 ...

Deposition rates of atmospheric particles were determined using previously published 210Pb data in soils and air. The dry deposition velocities for moorland and woodland soils were 2.2±1.8 and 9±2 mm• s-1, respectively. ...

This paper reports the γ-radiation levels of the naturally occurring 40K, 210Pb, 232Th and 226Ra and the anthropogenic 137Cs in the eastern part of Botswana so as to assess their possible dose impact to the members of the ...
