An article, such as a containment system (10), having sides (12) with walls (2) or (24) is made; in one method by using cast, cooled, melted, radioactive metal components where the melted metal has a specific activity over 130 Bq/g; or by providing a contaminated material in the form of a solid, liquid or mixture, and then mixing the contaminated material, to which no more than about 15 weight % of uncontaminated material has been reacted, with a binder, followed by forming the composition into a containment system and then curing it into a mass which contains both contaminated material, and uncontaminated binder acting as a matrix for the contaminated material. This article need not be a containment system but can be a wide variety of objects which are made out of radioactive waste, hazardous waste, and their mixtures.
