Retrospective dosimetry for external exposures

International Congress Series, 2002
Abstract Two methods of retrospective dosimetry for external exposures are reviewed. First, electron paramagnetic resonance (EPR or electron spin resonance, ESR) with teeth has its strengths in the determination of individual exposures, acute or protracted, that may have occurred several decades ago. The method is best studied for photon fields. The

Investment in manufacturing, exchange rates and external exposure [PDF]

Journal of International Economics, 1995
Abstract This paper introduces a new measure of external exposure, which emphasizes exposure to external markets both through export sales and imported inputs into production, and uses this measure to explore the linkage between exchange rates and investment in US industry.

OCCUPATIONAL EXPOSURE TO EXTERNAL RADIATION IN SWITZERLAND

Radiation Protection Dosimetry, 2016
Individual monitoring for both external and internal exposures is well regulated in Switzerland. The article gives an overview on the occupational exposure to external radiation of workers based on the data collected in the Swiss national dose registry (NDR) in 2013.

EXTERNAL AND INTERNAL EXPOSURE TO FUKUSHIMA RESIDENTS

Radiation Protection Dosimetry, 2016
The Great East Japan Earthquake of 11 March 2011, caused the Fukushima Daiichi Nuclear Power Plant Accident, which resulted in the release of a large amount of radioactive materials into the environment, and there is a serious concern about the radiation effects on the health of residents living in the affected areas. The evaluation of exposure dose is

Electromagnetic Exposure from a WBAN and External Transmitters

2019 13th International Symposium on Medical Information and Communication Technology (ISMICT), 2019
A Wireless Body Area Network (WBAN) consisting of several wearable slot antennas working in the 2.4 GHz frequency band is presented. The transmission coefficients between the different wearable devices are investigated, as well as the communication links with external sources. Electromagnetic exposure levels due to the antennas of the WBAN are assessed

External Radiation Doses from Occupational Exposure

Nature, 1969
Records accumulated between 1960 and 1965 of radiation doses received by a wide range of radiation workers in the United Kingdom have been summarized. Doses were generally small.

EXTERNAL EXPOSURE MODEL IN THE RESRAD COMPUTER CODE

Health Physics, 2002
An external exposure model has been developed for the RESRAD computer code that provides flexibility in modeling soil contamination configurations for calculating external doses to exposed individuals. This model is based on the dose coefficients given in the U.S. Environmental Protection Agency's Federal Guidance Report No.

External radiation exposure of personnel working with 99mTechnetium

European Journal of Nuclear Medicine, 1982
Radiation from 99mTc was measured at typical locations in those areas of a nuclear medicine department where approximately 50 Ci 99mTc is used per year. In addition, measurements of shielded and unshielded syringes containing 99mTc-labelled radiopharmaceuticals were carried out.

External Septorhinoplasty—Exposure for the Difficult Nose

Annals of Plastic Surgery, 1989
External septorhinoplasty affords direct exposure, which allows both the novice and the expert surgeon to treat the most challenging noses with a higher degree of assurance. Criticism of the external columellar scar is unwarranted. The technique is reviewed in detail, and complex cases are illustrated.

Dependence of fluorescence in phytoplankton on external exposures

Biophysics, 2015
Phytoplankton is the main source of oxygen and the primary link in the food chain for water objects; it plays an important role in their ecological status. In determining the concentration by fluorescence, the effect of parameters of the medium on the fluorescence intensity is not considered.
