Determination of the number size distribution of submicron atmospheric aerosols using a differential mobility particle sizer
(North-West University (South Africa), 2013)Ultra-fine aerosol particles may contain excessive amounts of harmful substances that can be easily inhaled and eventually enter into the human blood stream. The objective of this study was to determine the number size ... -
Determination of the occurrence of toxic trace metals at two sites in the North West Province using size of atmospheric aerosols
(2012)The concentration levels of atmospheric aerosols of different sizes of particulate matter namely PM 10, PM 2.5, PM 1 and PM <1 were determined in the North West province mining towns of Rustenburg which is a platinum ... -
Measurement of the equilibrium factor between radon and its progeny in the underground mining environment
(North-West University (South Africa), 2002)In an undisturbed area with little air circulation, the short-lived radon daughters will come into equilibrium with the parent radon, that is, the concentration ( measured in Bq / m3 ) of radon in air will be equal to ... -
Natural radioactivity concentrations and occurrence of heavy Metals in Shore Sediments along the Coastline of the Erongo Region in Western Namibia
(North-West University (South Africa), Mafikeng Campus, 2016)Some human activities like uranium mining, sea port activities and improper wastes handling has been identified as potential sources of exposure to naturally occurring radioactivity materials (NORM) and heavy metals. ... -
Silicon diodes fabricated on defect-engeneered material for use as radiation detector
(North-West University (South Africa), 2009)Current-voltage and capacitance-voltage measurements have been carried out on uradiated commercially available silicon p-i-n photodiodes under illumination of different wavelengths. The photodiodes were irradiated by 1 ... -
The study of the deterioration of Fe-Cr-Ni alloys by Mössbauer spectroscopy
(North-West University (South Africa), 2000)Duplex stainless steels (alloys) with chromium content in the ferritic phase greater than 13% are subject to embrittlement due to hardening of the ferrite phase. Some components of the primary loops of Pressurised Water ...
