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

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.

Occupational exposure to rare earth elements: Assessment of external and internal exposure

Environmental Pollution, 2022
Our study investigated occupational exposure to rare earth elements (REEs) in a major REE processing plant from North China by assessing both external exposure and internal exposure in the workers. An exposure group, including 50 workers in the processing plant, and a control group, including 50 workers from a liquor factory located 150 km away from ...

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

LEUKOCYTAL INDICES AND OCCUPATIONAL EXTERNAL GAMMA-EXPOSURE

Proceedings of The 16th Russian National Congress with International Participation «OCCUPATION and HEALTH», 21-24 September 2021, Vladivostok, 2021
Abstract. Background: The hematopoietic system is classified as the most radiosensitive body system. Research of occupational radiation-induced hematological shifts continues to be a relevant question of occupational radiation safety. Aim: Analysis of leukocytal indices dynamics depending on the accumulated dose of occupational external gamma-exposure.

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 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.

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.

Source Evaluation of the External Exposure

2016
This chapter is devoted to characterize main source terms of primary and secondary particles for external exposure. The assessment of neutron, photon and electron yield is detailed in usual physical process such as: fission reactions, ion interactions, bremsstrahlung on thick targets, induced activity in materials...
