The study is based on 44 questionnaires carried out with workers and ex-workers of Rössing, Two questionnaires were designed, one for former and one for current mineworkers. 12 respondents are former workers and 32 are still employed with Rössing. A previous study done by LaRRI in 2009 focused on the general working conditions whereas this study attempts to establish a connection between occupational exposure to low level radiation and toxicity, and the health condition of workers. Rössing has improved safety and health policies during the years of operation. When Rössing started production of uranium in 1976, no safety and health policies were in place. According to the statements of the workers, currently safety measures are high; the workers are trained on a regular basis and undergo refresher courses once a year. Despite this, some workers still confuse dust with radiation and believe wearing protective equipment protects them from radiation. In fact, protective equipment limits exposure (for example limiting dust inhalation) but does not protect workers from ionising radiation.
