SOME METROLOGICAL CHARACTERISTICS OF THE NEW SECONDARY STANDARD FOR BETA RADIATION

In Brazil, beta radiation metrology was based on a 30-years-old irradiation system. Aiming to fulfill a regional metrological gap and safety requirements, a new secondary standard for beta radiation – the BSS2- was installed at the CDTN/CNEN. Results of three metrological characteristics of the BSS2 are presented.

REACTIVE METROLOGY OR PROACTIVE METROLOGY - WHICH APPROACH WILL BEST MEET THE GRAND CHALLENGE OF SUSTAINABLE DEVELOPMENT?

The traditional modus operandi of the National Metrology Institutes has been the development, realisation and dissemination of the SI Units. However sustainable development poses challenges for our economies and societies that do not neatly align themselves with the SI Unit divisions of mass, length, time etc. Whilst the need for the NMIs to support the core mission is not questioned, this paper examines the case for top-level metrology to play a far more proactive role in rising to the grand challenges of the future.

THE LEGAL METROLOGY BRAZILIAN MODEL

Objectifying to present the legal metrology Brazilian model, this article will concept its aspects, showing the characteristics, procedures and the main lines. In this context, the National Institute of Metrology, Standardization and Industrial Quality (Inmetro - Instituto Nacional de Metrology, Standardization e Qualidade Industrial – Instituto Nacional de Metrologia, Normalização e qualidade Industrial), considering its mission, the effective and efficient warranty of the activities in the whole country (Brazil has continental dimensions), the structure aimed for the legal metrology work is responsibility of the Legal Metrology Direction (Dimel – Diretoria de Metrologia Legal), with the support of the Metrological State Organizations (OME – Órgãos Metrológicos Estaduais) for that Inmetro has delegated the operational activities of metrological verifications and supervision of measurement instruments in use and pre-packed goods. This OME constitute the Brazilian Net of Legal Metrology and Quality – Inmetro (RBMLQ-I – Rede Brasileira de Metrologia Legal e Qualidade-Inmetro). Dimel does, directly, the Metrological Technical Regulation (RTM – Regulamento Técnico Metrológico) and the type approval of measurement instruments, being responsible for the management of the RBMLQ-I work.
The operation of the RBMLQ-I in accordance with Inmetro strategies and politics for legal metrology activities, including the normative prescriptions, the way of action, the appropiation act and the resources are primordial factors for the best attainment of the Institute’s mission, in the metrological guarantee of the measurements to the citizen protection and the consolidation of a free trade and a fair invitation to bid.

EUROMET – COORDINATING METROLOGY IN 21ST CENTURY EUROPE

EUROMET is the regional collaboration of National Metrology Institutes (NMIs) in Europe. Since the signature of the CIPM Mutual Recognition Arrangement in 1999 EUROMET has concentrated on the evaluation of CMCs and NMI quality systems. Meanwhile, the iMERA project is exploring the many issues associated with a coordinated metrology research programme. Plans for a research network will be well advanced by the time of the IMEKO Congress.

IMPLEMENTING METROLOGY IN THE EUROPEAN RESEARCH AREA – THE iMERA PROJECT

Advances in metrology underpin innovation, enable improvements in quality of life, and unlock potential from other areas of science. Increased demand for top-level metrology in traditional areas, allied with the need to support emerging areas of technology, requires a new approach from the European NMIs. Increasing levels of cooperation in R&D will enable the NMIs to significantly improve impact from funding that can not reasonably expected to keep pace with demand growth. Within the iMERA project a coordinated European Metrology Research Programme will be prepared and the institutional and legal conditions for its implementation will be generated.

EUROPEAN FORESIGHT PROCESSES ON METROLOGY R&D

The background and the results of a first investigation on national foresight processes carried out in European countries, and what we learned from it, are here presented. This work is one of the basic tasks of the European project “iMERA” started in 2005. A questionnaire provided detailed information on the national activities of metrology foresight, in particular, information on:
- the number of countries performing foresight processes in metrology or in related areas,
- the number and the typologies of foresight processes in different metrology fields,
- the methodologies used,
- the frequencies of the foresight processes and the dissemination of related results,
- the level of participation of NMIs to national foresight processes and their feeling about the real utility of these kind of activities.
The survey gave an overview of the present state-of-the art of the metrology foresight processes, by focusing mainly on their characteristics rather than on their contents. The analysis show a large variety of national foresight processes on metrology R&D ranging from solid and highly formalised procedures to a much more informal and simple methodology. Many reported studies seem to have the characteristics of Forecasting and Strategic Planning rather than of Foresight exercises.

PRACTICAL EXPERIENCE OF THE CIPM MRA - THE VIEW FROM AN NMI ”USER”

The mutual recognition of national measurement standards and of calibration and measurement certificates issued by national metrology institutes (NMIs) was signed in October 1999. Since then the NMIs have striven to develop and effectively implement the CIPM MRA. Following the completion of the transition period, this paper describes those activities from an NMI’s viewpoint, the lessons learnt and the challenges to be faced in the future, including ensuring that the benefits of the CIPM MRA are taken out into the wider international community and that the CIPM MRA can be developed and sustained in the long term.

DEVELOPMENT OF DATA TREATMENT SOFTWARE FOR CALIBRATION OF NONINVASIVE MEASUREMENT OF X-RAY TUBE POTENTIAL

A data treatment software that serves as support for high voltage dividers in the non-invasive meters calibration is presented. This software calculates quantities like the absolute peak potential, maximum peak potential, average peak potential, practical peak voltage, ripple, average current, exposure time and current-time product through voltage and current waveforms. The software was evaluated using theoretical waveforms, where it showed that works correctly. In this work is also presented the results obtained with the analysis of voltage and current experimental waveforms.

DEVELOPMENT OF A DATA POST PROCESSING PROGRAM OF IMAGE SIMULATION WITH MCNP5

A post processing program used to convert MCNP5 radiographic tally output for use with external graphics programs is presented. This program was evaluated through analysis of geometric and physical parameters in simulated images. The results show good agreement with teorical values.

EMISSION RATE CORRECTIONS FOR 241AmBe SOURCES IN MANGANESE BATH OF LNMRI/IRD

This work tries to get better: uncertainties and accuracy for determination of bath losses. With simulation is possible to individualize calculations from all the loss components, for each specific measurement. A regression model is also evaluated based on an old and a new proposed model.
