Purpose To present the acceptance and the commissioning, to define the reference dose, and to prepare the reference data for a quality assessment (QA) program of an ultra-high dose rate (UHDR) electron device in order to validate it for preclinical animal FLASH radiotherapy (FLASH RT) experiments and for FLASH RT clinical human protocols. ...
Several studies, performed both through Monte Carlo simulation of dosimetric and microdosimetric enhancement in presence of GNPs and through in–vitro experiments, have clearly shown the powerfulness of such a technique in radiotherapy. ...
This paper presents the two new palladium brachytherapy sources, IR03- 103 Pd and IR04- 103 Pd that have been developed at Agricultural, Medical & Industrial Research School . The dosimetric parameters, such as the dose rate constant Λ , the radial dose function g ( r ) and the anisotropy function F ( r , θ ), around the sources have been characterised ...
It is observed that the glow curves of the nanomaterial exposed to these ions are similar to that exposed to gamma rays, with a dosimetric peak at 462 K beside a smaller one at 503 K, while those of the microcrystalline sample exposed to both ion beams and gamma rays have their prominent peak at 503 K beside a smaller one at 462 K. ...
The aim of this work is to introduce a new dosimetric approach that is expected to contribute to characterising and distinguishing low, intermediate and high dose ranges. ...
Experience in individual dosimetric and radiometric surveys of the public during the early phase of the Chernobyl accident has been considered. ...
Materials and methods: the database of the Regional Medicodosimetric Register (RMDR) of SGCE personnel includes information about personnel, dosimetric and the medical character of the disease. We have completed forming the cohorts of reactor production (RP) and radiochemical production (RCP) workers. ...
A Branch Medical Dosimetric Registry (BMDR) of atomic industry and nuclear power employees is under development in Russia to amalgamate a number of regional registries. ...
Unique information from the medical dosimetric register of the IC 'Mayak' personnel (SUrIBPh) was used relating to the starting period of the beginnings of the Russian nuclear branch, when the personnel were exposed to doses that exceeded all modern standards. Earlier (2–5 years after the beginning of exposure), the dynamics of leukaemia morbidity was found among the personnel ...
The registry design principles are subdivided into three groups as follows: economic and mathematical principles; systemic principles; organisational and technical principles.Keywords: medical-dosimetric register, automated registry design, directive materials, information technology, medical statistics, design principles, data ...
Health protection requires reliable monitoring and accurate dosimetric devices Conventional methods include paper badges that change colour and turn red (or sometimes blue) when exposed to Phosgene. ...
The minor discrepancy between the DDREF of 2 recommended by the ICRP and the estimate of the low-dose extrapolation factor of about 1.5 that is derived here for solid tumours and leukaemias is unremarkable.Keywords: A-bomb survivors, dose and dose-rate effectiveness factor, DDRF, Japan, leukaemia, dosimetric error, solid tumors, cancer risks, ionising radiation, radiological ...
Given the similarity of the leukaemia mortality and incidence datasets, the reasons for this difference are not entirely clear, but the most likely explanation is the finer disaggregation of dose groups in the publicly available version of the leukaemia mortality data compared with the incidence data.Keywords: A-bomb survivors, threshold, leukaemia, dosimetric error, low ...
The linear excess relative risk coefficient of breast cancer incidence in the Japanese A-bomb survivor data, however, is significantly higher (two-sided P = 0.04) than that in the Massachusetts TB fluoroscopy data; this remains the case (two-sided P = 0.03) if account is also taken of possible curvature in the A-bomb survivor dose response and random dosimetric errors. The best ...
