Monte Carlo-based Investigation of Absorbed-dose Energy Dependence of Thermoluminescent Dosimeters in Therapeutic Proton and Carbon Ion Beams

Journal of Medical Physics
Background: The present study is aimed at calculating relative absorbed-dose energy response correction (R) of commonly used thermoluminescent dosimeters (TLDs) such as LiF, Li2B4O7, and Al2O3 as a function of depth in water for protons (50–250 MeV/n ...

Influence of photon, proton and carbon ion irradiation on differentiation, maturation and functionality of dendritic cells

Frontiers in Bioscience-Scholar, 2022
While the primary purpose of radiotherapy (RT) is the elimination of cancer cells by inducing DNA-damage, considerable evidence emerges that anti-neoplastic effects extend beyond mere tumor cell killing. These secondary effects are based on activation of

Study of light ions acceleration in a diode with a solid target and registration of nuclear proton-boron reaction products generated in the plasma diode [PDF]

Ядерна фізика та енергетика
The results of proton fluxes registration and the nuclear reactions (p + 11B > 3α) they induce on boron-containing targets in a plasma diode pinch, generated by irradiation of the anode target with a relativistic electron beam, are presented.

Optically stimulated luminescent response of the LiMgPO4 silicone foils to protons and its dependence on proton energy

, 2023
The prototype of the LiMgPO4 (LMP) silicone foils has been tested to find their OSL relative response to protons and their dependence on proton energy. The proton depth–-dose distribution was measured for the pristine monoenergetic 58 MeV Bragg Peak (BP)

Water, Protons, and the Gating of Voltage-Gated Potassium Channels

Membranes
Ion channels are ubiquitous throughout all forms of life. Potassium channels are even found in viruses. Every cell must communicate with its surroundings, so all cells have them, and excitable cells, in particular, especially nerve cells, depend on the ...
