Assessment of γ-radiation levels and associated dose rates from surface soils in the eastern part of Botswana
Likuku, Sello Alfred; Karunakara, Naregundi; Nthoiwa, Gothatamang Patrick (INDERSCIENCE Publishers, 2014)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 ... -
Atmospheric transfer and deposition mechanisms of 210Pb aerosols onto forest Soils
Likuku, Sello Alfred (Springer Verlag, 2009-09)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 ... -
Deposition rates of atmospheric particulates determined from 210Pb measurements in soils and air
Likuku, Sello Alfred; Branford, Derek (HARD Publishing, 2010)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. ... -
The influence of exogenously applied 2,4- dichlorophenoxyacetic acid on fruit drop and quality of navel oranges (Citrus sinensis L.)
Modise, D. M.; Likuku, Sello Alfred; Thuma, M.; Phuti 2, R. (Academic Journals, 2009-05-18)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 ...
