This patent describes a vacuum system having a vacuum source for collecting radiologically contaminated material for disposal, comprising: an inlet nozzle for collecting the material; a cyclone separator connected to the inlet nozzle to receive the material. The cyclone separator has a material discharge and an air flow discharge; a product container positioned at the material discharge for receiving material discharged from the cyclone separator. The product container is transparent for allowing observation of a level of material collected; a first prefilter downstream of the air flow discharge for filtering air from the air flow discharge; a second prefilter connected between the vacuum source and the first prefilter for filtering air from the first prefilter. The second prefilter has means for visually observing the air flow in the second prefilter; means for monitoring a pressure drop across the first prefilter; and means for supporting the product container against the material discharge during operation and for facilitating removal of the product container from the material discharge for disposal of the material.
