Abstract

Digital Preservation test‐bed is a three‐year practical research project with the overall goal of investigating options to secure sustained accessibility to authentic archival records over the long‐term, by carrying out experiments in a controlled and secure environment. This allows one to ascertain the effects of undertaken preservation action on archival records. Test‐bed is researching three different approaches to long‐term digital preservation: migration, XML and emulation. Not only will the effectiveness of each approach be evaluated, but also their limits, costs and application potential. Experiments take place on four different record types: text documents, spreadsheets, emails and databases of different size, complexity and nature. At the end of 2003 the digital preservation test‐bed project was to provide: advice on how to deal with current digital records, recommendations for an appropriate preservation approach or a combination of approaches per record type, functional requirements for a preservation function, cost models of the various preservation strategies, a decision model to select the right preservation strategy, and recommendations concerning archival guidelines and regulations.

Abstract

The Medical Research Council's Committee has issued its Second Report on Hazards to Man of Nuclear and Allied Radiations. From time to time we report on the monitoring of foods for radioactive substances, mainly Strontium 90, by the laboratories of the Agricultural Research Council and a few local authorities. The “maximum permissible levels” of radiation for individuals to which these measurements are related are those contained in the Committee's First Report (1956). Since this much work has been done making increasing numbers of measurements. In particular, background radiation from natural sources has been measured in detail. This constitutes the largest dose of radiation to the ordinary population—an average annual doserate in millirads in the range of 85 to 106. In comparison, radiation from its increased use in modern life and also from radioactive fall‐out is extremely small. Medical radiological procedures, after a nation‐wide survey of hazards to patients, are not so important as was first believed, but nonetheless contribute a larger dose than any other source of man‐made radiation, approximately 19 millirads per annum. The Adrian Committee, which conducted the review of radiological practice, considered that the dose could be reduced to 6 mr., without curtailment of radiological services.
