Measurement of environmental warmth in SI units.
Ellis, F. P., Smith, F. E., and Walters, J. D. (1972). Brit. J. industr. Med., 29, 361-377. Measurement of environmental warmth in SI units. Although 'Environmental Warmth and Its Measurement' (Medical Research Council War Memorandum No. 17), written over 25 years ago for the Royal Navy, is still widely used and has not been revised, the validation and amplification of the methods proposed by t...
متن کاملSI units.
SI Units The International System of Units (SI) is system of units of measurements that is widely used all over the world. This modern form of the Metric system is based around the number 10 for convenience. A set unit of prefixes have been established and are known as the SI prefixes or the metric prefixes (or units). The prefixes indicate whether the unit is a multiple or a fraction of the ba...
متن کاملDimensionless units in the SI
The International System of Units (SI) is supposed to be coherent. That is, when a combination of units is replaced by an equivalent unit, there is no additional numerical factor. Here we consider dimensionless units as defined in the SI, e.g. angular units like radians or steradians and counting units like radioactive decays or molecules. We show that an incoherence may arise when different un...
متن کاملRadiation Protection in Diagnostic Radiology
This paper summarizes technological advances in diagnostic radiography, fluoroscopy and computed tomography, mainly the developments in digital detectors and helical CT scanners with multiple-row detectors. It reviews dosimetric concepts and presents the most up-to-date information on the global patterns of use of radiological modalities as well as the trends in diagnostic medical exposure dose...
متن کاملRadiation Protection in Interventional Radiology
Interventional procedures are used by a significant number of medical specialities. Radiation protection (RP) for patients and staff is one of the main issues in Interventional Radiology (IR). UNSCEAR, ICRP and IAEA have devoted significant time over the last years to improve radiation safety in IR. Several combined factors: prolonged localized fluoroscopy, multiple radiographic exposures, and ...
