Simultaneous personal measurements of the occupational ultraviolet exposure weighted to the International Commission on Non-Ionising Radiation Protection hazard sensitivity spectrum (UVICNIRP) were made over a five week period (44 person-days) in the second half of the summer school term of 2012 in Queensland, Australia for individual high school teachers located at latitudes of 27.5°S and 23.5...

This paper presents a comparison performed between two calibration laboratories in several radiation qualities, using dosimeters of varying quality as transfer instruments. The goal this work was to investigate the viability field-class for official comparisons and determine if factors are comparable within stated measurement uncertainties. results were acceptable high-quality electronic person...

The use of polymer gels to record radiation dose distributions in three dimensions was first proposed in 1992 as a proof-of-principle [1]. The accuracy of these early polymer gel dosimeters and scanning methods was not sufficient for most clinical applications [2]. Since then, several efforts were made to increase the accuracy and precision of both the physical gel dosimeter and the scanning te...

Abstract Cancer prevention and treatment are currently the focus of most research. Dose verification is an important step for reducing improper dose deposition during radiotherapy. To mend traditional gel dosimeters 3D verification, a novel rare-earth nanoparticle-based composite was prepared, which has good radioluminescence property reusability. It promising phantom material new dosimeter. TE...

Spectrophotometry has been the conventional technique for measuring optical density of irradiated gels [1]. Later, magnetic resonance imaging (MRI) was found to be capable of imaging radiation dose patterns in 3D [2]. Optical methods are still under investigation in the form of optical tomography [3– 6]. They promise to give three dimensional dose distributions without the cost attached to MRI....

As a part of the China-Japan cooperative research on natural radiation epidemiology, we have carried out a dose-assessment study to evaluate the external exposure to natural radiation in the high background radiation areas (HBRA) of Yangjiang in Guangdong province and in the control areas (CA) of Enping prefecture since 1991. Because of the difficulties in measuring the individual doses of all ...

In this study, the field performance of two coverall designs used by pesticide applicators was determined. Two coverall types were selected based on data from previously conducted comfort testing under field conditions in southern Europe. Dermal exposure was measured during 22 applications conducted with 11 operators using similar hand-held spray guns in greenhouse pepper crops in the Ierapetra...

This work evaluated the Hp(10)dose for the personnel exposed in mixed field inside several locations of reactor 1 building at Cernavoda NPP. In order to achieve this we used active (EPD N2 and DMC 2000GN) and passive (TLD 8806) personnel dosimeters and one ambient neutron monitor for H*(10) evaluation. The dose correction coefficients vary from one room to another depending on the neutron spect...
