Microdosimetry Study of Proton Quality Factor Using Analytic Model Calculations
Applied Sciences, 2022 The quality factor (Q) is formally linked to the stochastic (e.g., carcinogenic) risk of diverse ionizing radiations at low doses and/or low dose rates.

Proton relative biological effectiveness (RBE): a multiscale problem. [PDF]
Br J Radiol, 2019 Proton radiotherapy is undergoing rapid expansion both within the UK and internationally, but significant challenges still need to be overcome if maximum benefit is to be realised from this technique. One major limitation is the persistent uncertainty in proton relative biological effectiveness (RBE).

Rapid RBE-Weighted Proton Radiation Dosimetry Risk Assessment [PDF]
, 2016 Proton therapy dose is affected by relative biological effectiveness differently than X-ray therapies. The current clinically accepted weighting factor is 1.1 at all positions along the depth–dose profile.

Clinical consequences of relative biological effectiveness variations in proton radiotherapy of the prostate, brain and liver [PDF]
, 2013 Proton relative biological effectiveness (RBE) is known to depend on the (alpha/beta)(x) of irradiated tissues, with evidence of similar to 60% variation over (alpha/beta)(x) values from 1-10 Gy.

The relative biological effectiveness of antiprotons
Radiotherapy and Oncology, 2016 Aside from the enhancement of physical dose deposited by antiprotons annihilating in tissue-like material compared to protons of the same range a further increase of biological effective dose has been demonstrated. This enhancement can be expressed in an increase of the relative biological effectiveness (RBE) of antiprotons near the end of range.

Basics of particle therapy II: relative biological effectiveness [PDF]
Radiation Oncology Journal, 2012 In the previous review, the physical aspect of heavy particles, with a focus on the carbon beam was introduced. Particle beam therapy has many potential advantages for cancer treatment without increasing severe side effects in normal tissue, these kinds of radiation have different biologic characteristics and have advantages over using conventional ...

Estimating the Relative Biological Effectiveness of Auger Electron Emitter 123I in Human Lymphocytes
Frontiers in Physics, 2020 Auger electron emitters are considered to be a promising strategy for targeted radionuclide therapy of metastatic diseases, given their high linear energy transfer (LET) and short range in tissue which could potentially limit normal tissue toxicity ...
