Optically stimulated nanodosimeters with high storage capacity [PDF]
, 2019 In this work we report on the thermoluminescence (TL) and optically stimulated luminescence (OSL) properties of beta-Na(Gd,Lu)F-4:Tb3+ nanophosphors prepared via a standard high-temperature coprecipitation route. Irradiating this phosphor with X-rays not

Playing Hard with Si: Challenges and Opportunities for New Materials in Radiation Therapy Dosimetry
Advanced Materials, EarlyView.Silicon has been a cornerstone material of radiation therapy dosimetry for many decades, providing somewhat unchallenged performance. However, there are caveats to its use, requiring complex designs and, often, correction factors to provide accurate measurements.

Advanced Science, EarlyView.Single‐cell RNA sequencing reveals distinct immune responses to FLASH versus conventional dose rate irradiation in early radiation‐induced lung injury. FLASH irradiation reduces Ccrl2⁺ neutrophil infiltration, activates CD4⁺ CD40L⁺ Th cells, restrains pro‐inflammatory Mefv⁺ monocytes, and enhances epithelial repair via TGF‐β signaling, underscoring its

Development of two dosimeters for industrial use with low doses [PDF]
Nuclear Technology and Radiation Protection, 2017 The present study involves a comparison between two dosimetry systems. The first system depends on victoria blue B (incorporating polyvinyl alcohol) as a thin-film dosimeter. The second system depends on the same dye as a liquid dosimeter, which

Patterns in the received facial UV exposure of school children measured at a subtropical latitude [PDF]
, 2008 Polysulphone dosimeters have been employed to measure the erythemally effective UV exposure to the vertex, nose, cheek, chin and side facial sites of 45 volunteer high school students from Hervey Bay, Australia (25.3oS 152.9oE).

Dosimetric characteristics of a new linear accelerator under gated operation. [PDF]
, 2006 Respiratory gated radiotherapy may allow reduction of the treatment margins, thus sparing healthy tissue and/or allowing dose escalation to the tumor. However, current commissioning and quality assurance of linear accelerators do not include evaluation ...
