Uranium mining and processing are associated with a wide range of potential adverse human health risks. Some of these risks arise out of aspects of uranium mining and processing specific to that enterprise, whereas other risks apply to the mining sector generally and still others are linked more broadly to largescale industrial or construction activities.
The next step in the hazard management process, as shown in Figure, is to determine the level or risk associated with the hazard once it has been identified. The hazards analysis team must decide if their discussions are to focus on highrisk or highconsequence events. Either approach is valid, but the team members must be clear as to ...
