Why Do Some Reports Claim that the Number of COVID-19 Hospitalized Smokers is Smaller than Expected? [PDF]

open access: yesJournal of Biomedical Physics and Engineering, 2020
Researchers believe that smoking might increase the severity of infections caused by SARS-CoV-2 by altering the viability and integrity of the BBB, while promoting the expression of ACE2 in endothelial cells, glia, and neurons.

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]

open access: yesЯдерна 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.

High scintillation yield and fast response to alpha particles from thin perovskite films deposited by pulsed laser deposition

open access: yesFrontiers in Physics, 2022
Although the field of solar cells is the most popular application of perovskite materials, their use in radiation detection applications is emerging. The success of perovskites as radiation detectors rests partly on the same material properties that have

Response of 4H-SiC Detectors to Ionizing Particles

open access: yesCrystals, 2020
We report the response of newly designed 4H-SiC Schottky barrier diode (SBD) detector prototype to alpha and gamma radiation. We studied detectors of three different active area sizes (1 × 1, 2 × 2 and 3 × 3 mm2), while all detectors had the same 4H-SiC ...

Strong Shift to ATR-Dependent Regulation of the G2-Checkpoint after Exposure to High-LET Radiation

open access: yesLife, 2021
The utilization of high linear-energy-transfer (LET) ionizing radiation (IR) modalities is rapidly growing worldwide, causing excitement but also raising concerns, because our understanding of their biological effects is incomplete.

Alpha-Particle Spectrograph [PDF]

open access: yesReview of Scientific Instruments, 1951
An alpha-particle spectrometer, using a 60° sector magnet capable of focusing alpha-particles of energies up to 14 Mev, is described. Description of the instrument, sample technique, focusing properties, and current supplies are discussed. Transmission is about 0.01 percent of the total solid angle of the sample and with a resolution of 8 kev.

Hourly measurement method for radon progeny volumetric activity in air

open access: yesJournal of Environmental Engineering and Landscape Management, 2007
A method of radon progeny volumetric activity hourly measurement in air was created. A radiometer, which measures the activity of a filter band through which air is sucked, was installed in a hermetic metal frame. Radiometer data was recorded and sent to

The Impact of the Normality of Two Types of Chemical Solutions on the Etching Rates of Nuclear Track detector CR-39 [PDF]

open access: yesKirkuk Journal of Science, 2023
Solid-state nuclear track detectors such as CR-39 are used in the detection of charged particles and heavy ions. In this paper, the effect of two types of chemical etching solutions on the etching properties of the detector CR-39 of 400 µm thickness was ...
