Quantifying uncertainty in calibration and clinical application of EBT-4 Gafchromic film dosimetry. [PDF]

open access: yesMed Phys
Abstract Background GAFchromic films (GAFs) are essential tools in radiotherapy dosimetry, but uncertainties in calibration methods limit their accuracy and hinder consistency across clinical practice. Purpose This study aimed to perform a comparative analysis of different calibration functions for GAFchromic EBT4 films in single‐ and double‐channel ...

Characterization of the collimated output fluence , in a thermal neutron field, in terms of ambient equivalent dose H*(10,0)

open access: yesBrazilian Journal of Radiation Sciences, 2022
The Brazilian Neutron Laboratory at the Institute of Radioprotection and Dosimetry (IRD) developed and built a new standard facility for thermal neutron flux, seeking to provide a new homogeneous fluence to calibrate neutron detectors and personal ...

Comparison of a personalized breast dosimetry method with standard dosimetry protocols [PDF]

open access: yesScientific Reports, 2019
AbstractAverage glandular dose (AGD) in digital mammography crucially depends on the estimation of breast glandularity. In this study we compared three different methods of estimating glandularities according to Wu, Dance and Volpara with respect to resulting AGDs.

Cost-effective personal radiation dosimetry [PDF]

open access: yesLithuanian Journal of Physics, 2009
Deep understanding of physical properties of the materials under the inuence of radiation exposure is vital for the effective design of dosimeter devices. Detection of radiation is based on the fact that both the electrical and the optical properties of the materials undergo changes upon the exposure to ionizing radiation. It is believed that radiation

Dosimetry, personal monitoring film

open access: yesPhilosophy of Photography, 2011
The article focuses on radiation dosimetry, which made use of the photographic film known as Type 2 Monitoring Film (Kodak) to detect and measure harmful ionizing radiation. It explores the implications of the demise of this technology in relation to Henri Van Lier's critique of photographic indexicality in his paper "Towards a Philosophy Instigated by

First-in-man evaluation of 124I-PGN650: A PET tracer for detecting phosphatidylserine as a biomarker of the solid tumor microenvironment [PDF]

open access: yes, 2017
Purpose: PGN650 is a F(ab′) 2 antibody fragment that targets phosphatidylserine (PS), a marker normally absent that becomes exposed on tumor cells and tumor vasculature in response to oxidative stress and increases in response to therapy.

Personal dose assessment using thermoluminescent dosimetry [PDF]

open access: yesAIP Conference Proceedings, 2021
We present results of the development of two personal dosimetry devices, called 4-FRD and Koph/Shin, based on thermoluminescent dosimeters. 4-FRD uses TLD-100 and different filters, while Koph/Shin uses a TLD-100/TLD-300 combination. These devices were calibrated for 15-1250 keV photons (4-FRD) and 15-65 keV (Koph/Shin), in terms of air kerma.

The Early Days of Personal Solar Ultraviolet Dosimetry

open access: yesAtmosphere, 2020
In the early 1970s, environmental conservationists were becoming concerned that a reduction in the thickness of the atmospheric ozone layer would lead to increased levels of ultraviolet (UV) radiation at ground level, resulting in higher population ...
