Decontamination of Radioactive Waste Air


Book Description

Contaminated waste air has been treated with a baffle-plate scrubbing tower with 42 plates in three stages. The air was sampled for activity before and after each stage and the effect of several process variables investigated. With only six plates per stage in use the efficiency for plain cold water washing was 99.6 percent or better, and was 99.92 percent for the cloud chamber mode of operation. Some data on particle size and preliminary engineering figures are given.




Handbook of Radioactive Contamination and Decontamination


Book Description

The objective of this book is to present a comprehensive picture, first of the fundamentals of general contamination of solid surfaces and water, and in the second part, to review the main practical procedures and means of applied decontamination used in the fields of activity. The most emphasis on radioactive contamination deals with decontamination of the operational facilities in nuclear power plants. Other special decontamination branches of current interest are also dealt with briefly.The art of decontamination is being enriched by the progress achieved in relevant scientific disciplines and employs these relative advances. The current volume discusses in detail the following trends in decontamination: Firstly, the development and use of new decontamination methods that are highly efficient, non-agressive to decontaminated materials, and economically feasible; secondly, the utilization of progressive elements of automation and robotics; thirdly, the development and use of such decontamination formulations that would minimize the volume of wastes and would produce wastes in a form in which they could be either easily further treated or safely disposed of without risk to human health or the environment; finally, the choice of suitable materials used both for the structural and the technological parts of nuclear installations with regard to their minimal contaminability and ease of decontamination.

Surface Contamination


Book Description

Surface Contamination presents the proceedings of first International Symposium on Surface Contamination, held at Gatlinburg, Tennessee in June 1964. The meeting discusses the potential hazards brought about by noxious contaminants on surfaces; the effects of contamination to human health and safety; and the integrity of scientific and technical machinery and products in meeting the exacting requirements. The book contains the work of experts from different technical and administrative disciplines. Areas covered include fundamental research on redispersible and evaporable contamination, including radioactive, biological, chemical, and abrasive contaminants. Administrative and technical problems on radioactive surface contamination control criteria; measurement techniques; environmental control of surface contamination; dissemination of airborne microorganisms; radioactive contamination control applications; biological and chemical surface contamination; insurance and economics; and decontamination are tackled as well. The text will be a good source of information for ecologists, environmentalists, chemists, biologists, students, and policymakers.










Strategy and Methodology for Radioactive Waste Characterization


Book Description

Over the past decade significant progress has been achieved in the development of waste characterization and control procedures and equipment as a direct response to ever-increasing requirements for quality and reliability of information on waste characteristics. Failure in control procedures at any step can have important, adverse consequences and may result in producing waste packages which are not compliant with the waste acceptance criteria for disposal, thereby adversely impacting the repository. The information and guidance included in this publication corresponds to recent achievements and reflects the optimum approaches, thereby reducing the potential for error and enhancing the quality of the end product. -- Publisher's description.
