Hazards of Uranium

Uranium mining and processing poses a tremendous threat to workers and the population in the surrounding areas through the release of radiation and exposure to heavy metals and chemicals.

Published in RESEARCH

Uranium has been considered both a radiological and also a heavy metal poison, following calcium in its distribution within the body, i.e. building up in bone, and with the principle target for toxicity being the lung and the kidney. Recently, it has been shown that uranium also targets the brain.

Johannesburg sits atop the world's most productive gold reef -- a staggering 40,000 tons of the precious metal has been mined from it during a history tracing back 130 years. That legacy of riches has left behind a toxic inheritance: radioactivity from uranium hauled up in the mining process.
Scientists have found uranium quantities in rivers west of the city to be as much as 4,000 times natural levels and in tap water as much as 20 times higher. A soil sample taken by Bloomberg News and tested by government-certified WaterLab Ltd. from pumpkin roots grown a little more than a mile from a recently closed gold mine contained five times more uranium than background levels considered normal by the International Atomic Energy Agency.

Mitigation measures at Uranium Mines

Uranium mining operations have high impacts on environment and society, and can lead to deterioration of health of workers and communities. Uranium mining activities are increasing in Africa, where mining is not always strictly regulated and controlled. Mitigation of negative impacts from uranium mines by national governments and international mining companies can have a positive effect on society and environment.
An assessment of the mitigation measures is addressed in the report "Uranium from Africa" by World Information Service on Energy (WISE) and Stichting Onderzoek Multinationale Ondernemingen (SOMO)


Centre for Research on Multinational Corporations.

 

The report assesses what mitigation measures governments and industry are taking in Namibia, South Africa, and the Central African Republic. Practices are compared with Canada and Australia, where regulation is more strict.

"It is surprising that South Africa has no specialised institutions which have adequate knowledge on the impacts of (uranium) mining operations and can monitor, educate, and advise on all mining-related health and environmental issues".

EXTRACTS from the report are contained in this article. The FULL REPORT is available to download.

Reprocessing tailings

The reprocessing of tailings by Rand Uranium is an important step forward in rehabilitation of an environment that has been badly scarred by earlier mining activities.

Uranium in the Karoo: what it may mean

The social and environmental costs associated with uranium mining are difficult to predict and regulate. By the time environmental and socio-economic consequences become noticeable, the mines have typically closed, changed ownership or become insolvent and thus cannot be compelled anymore to contribute to the remediation, either financially or through other actions. The trust funds are often substantially inadequate to address environmental impacts.

'Move campus or see you in court'

The management and lecturers of the Central Johannesburg College are likely to face off in court over the bosses' refusal to relocate a campus from the Crown Mines area.
