Apparatus and methods are provided for establishing the nature and level of radioactive sources within waste, particularly of a compactable nature. Detectors sensitive to low energy level radiation are provided with protection against dust contamination. Further detector configurations are provided to establish the presence of metallic material and/or higher energy level gamma emissions and/or detectors with a lower sensitivity to the emissions and/or detector configurations sensitive to neutrons are further provided.
