European survey of dental X-ray equipment

Radiation Protection Dosimetry, 2008
The implementation of an X-ray Quality Assurance (QA) program is a legal requirement in Europe as stipulated in the EU Council Directive 97/43/EURATOM (MED). A review of the literature has identified that European countries are performing some level of QA testing of their dental X-ray equipment, although the type and level to which testing is performed

Bragg x-ray survey spectrometer for ITER

Review of Scientific Instruments, 2012
Several potential impurity ions in the ITER plasmas will lead to loss of confined energy through line and continuum emission. For real time monitoring of impurities, a seven channel Bragg x-ray spectrometer (XRCS survey) is considered. This paper presents design and analysis of the spectrometer, including x-ray tracing by the Shadow-XOP code ...

REVIEW OF MASS CHEST X-RAY SURVEYS

JAMA: The Journal of the American Medical Association, 1952
As the community-wide chest x-ray survey has developed in recent years, it has become, today more than ever, a concentrated attack on tuberculosis. Through the use of the photofluorograph, we now screen entire communities—the adult population of whole cities or large metropolitan areas—and, in so doing, find tuberculosis and gather the information we ...
