|dc.description.abstract||Legislation requires the regular monitoring of all employees exposed to radiation in
their work environment. The monitoring of a-radiation, which is emitted by radon
gas, was the primary concern of this study. Radon comes from the natural decay of
uranium, which is a heavy metal found in all rock and soil.
The main objective of this study was to establish a controlled monitoring program
through which results could be obtained, captured and studied. The mine monitored in
this study had high radiation levels, requiring urgent and effective strategies to reduce
The study included five monitoring cycles which yielded comprehensive results.
Insight gained from these results made it possible to identify strategies to reduce the
high prevalence of exposure in the mine.
Results were compiled in a database and then used to predict each employee's annual
exposure. The personal history of each employee was also documented in the
database. Results revealed that proper administrative and ventilation controls were
effective in reducing exposure to radiation in the mining environment. Thus, the
hypothesis for this study was proven to be true.||
