Concepts of microdosimetry [PDF]

Radiation and Environmental Biophysics, 1975
This is the first part of an investigation of microdosimetric concepts relevant to numerical calculations. The definitions of the microdosimetric quantities are reviewed and formalized, and some additional conventions are adopted. The common interpretation of the quantities in terms of energy imparted to spherical sites is contrasted with their ...

A novel system for micron-scale analysis of energy deposition and response to low-dose radiation. [PDF]

Med Phys
Abstract Background Micrometer‐scale evaluation of energy deposition is important for radiation protection and therapy as well as for advancing knowledge of responses to radiation in materials and biological systems. Due to the stochastic nature of radiation interactions, there is significant variation in energy deposition in micrometer‐sized targets ...

Measurement of microdosimetric spectra of high-LET particle beams using the ENCORE detector. [PDF]

Med Phys
Abstract Background Heavy ion radiotherapy offers distinct advantages over conventional treatments due to its superior dose distribution and enhanced biological effectiveness. However, the microdosimetric characteristics of high linear energy transfer (LET) ions, particularly near the Bragg peak, remain poorly characterized.

Exploring the potential of Raman micro-spectroscopy of radiochromic films for experimental microdosimetry. [PDF]

Med Phys
Background Micrometer‐scale dosimetry is crucial when estimating the energy deposited within micrometer‐scale biological targets exposed to low doses or high dose gradients. Raman micro‐spectroscopy read‐out of radiochromic films (RCFs) permits micrometer‐scale resolution; this presents a novel opportunity to explore its feasibility for experimental ...

Equivalent relative biological effectiveness for cell survival and micronuclei formation: insights from a biophysical approach. [PDF]

Med Phys
Abstract Background Micronuclei (MN), which are chromosome fragments, are formed after exposure to ionizing radiation. Radiation‐induced MN is currently used as a quantitative indicator of the chromosomal aberrations detectable at a relatively early phase (e.g., within one cell‐cycle progression).

Playing Hard with Si: Challenges and Opportunities for New Materials in Radiation Therapy Dosimetry. [PDF]

Adv Mater
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.

Small dose monitor based on silicon-carbide diodes for FLASH radiotherapy. [PDF]

Med Phys
Abstract Background The FLASH biological effect in radiotherapy has been observed to appear at ultra‐high dose rates UHDR (>$>$40 Gy/s), where the accurate dosimetry at such high rates is still a challenge. Purpose A new 4 ×$\times$ 4 array of SiC‐based detectors (1 mm diameter, 2.2 mm pitch) is proposed for dosimetry in UHDR, as well as the ...

Progress in 3D Silicon Radiation Detectors

Frontiers in Physics, 2022
In the past few years, there has been an increasing interest toward 3D silicon radiation detectors. Owing to their unique architecture, 3D detectors provide a remarkable radiation hardness at relatively low bias voltage (hence low power dissipation ...
