Radioactivity determination in soil of Salah Al-Din governorate, Iraq.

Publication Type: Conference

Source(s): AIP Conference Proceedings. 2022, Vol. 2394 Issue 1, p1-9. 9p.

Abstract: The specific activity of naturally radionuclides (226Ra,212Pb and 40K) with artificial (137Cs) nuclide in soil samples were measured using NaI(Tl) scintillation detector for 30 different locations in Salah Al-Din Governorate, Iraq in 2020. The results ...

Radiation-Induced Rescue Effect: Insights from Microbeam Experiments.

Publication Type: Academic Journal

Source(s): Biology (2079-7737). Nov2022, Vol. 11 Issue 11, p1548. 29p.

Authors:

Abstract: Simple Summary: The present paper introduces a radiobiological phenomenon known as the Radiation-Induced Rescue Effect (RIRE), where the radiobiological effects developed in cells irradiated with ionizing radiations are mitigated by non-irradiated cell...

TOPAS-nBio simulation of temperature-dependent indirect DNA strand break yields.

Publication Type: Academic Journal

Source(s): Physics in Medicine & Biology. 7/21/2022, Vol. 67 Issue 14, p1-12. 12p.

Abstract: Current Monte Carlo simulations of DNA damage have been reported only at ambient temperature. The aim of this work is to use TOPAS-nBio to simulate the yields of DNA single-strand breaks (SSBs) and double-strand breaks (DSBs) produced in plasmids under...

The Influence of Different γ-Irradiation Patterns on Factors that May Affect Cell Cycle Progression in Male Rats.

Publication Type: Academic Journal

Source(s): Dose-Response. Jul2022, Vol. 20 Issue 3, p1-11. 11p.

Abstract: Most studies of the biological effects of ionizing radiation have been done on a single acute dose, while clinically and environmentally exposures occur under chronic/repetitive conditions. It is important to study effects of different patterns of ioni...

Searching for a Paradigm Shift in Auger-Electron Cancer Therapy with Tumor-Specific Radiopeptides Targeting the Mitochondria and/or the Cell Nucleus.

Publication Type: Academic Journal

Source(s): International Journal of Molecular Sciences. Jul2022, Vol. 23 Issue 13, p7238-N.PAG. 26p.

Abstract: Although 99mTc is not an ideal Auger electron (AE) emitter for Targeted Radionuclide Therapy (TRT) due to its relatively low Auger electron yield, it can be considered a readily available "model" radionuclide useful to validate the design of new classe...

Development of a portable hypoxia chamber for ultra-high dose rate laser-driven proton radiobiology applications.

Publication Type: Academic Journal

Source(s): Radiation Oncology. 4/15/2022, Vol. 17 Issue 1, p1-14. 14p.

Abstract: Background: There is currently significant interest in assessing the role of oxygen in the radiobiological effects at ultra-high dose rates. Oxygen modulation is postulated to play a role in the enhanced sparing effect observed in FLASH radiotherapy, w...

Computational simulator that calculates tumor control probability in a tumor heterogeneously irradiated for fractionated radiation oncology treatments.

Publication Type: Academic Journal

Source(s): Simulation. Apr2022, Vol. 98 Issue 4, p285-294. 10p.

Abstract: Although in the ionizing radiation field many concepts and processes are currently recognized as radiobiological, there are also probabilistic ones, and a probabilistic treatment makes a better understanding about them. The purpose of this study is to ...

The roles of intensity, exposure duration, and modulation on the biological effects of radiofrequency radiation and exposure guidelines.

Publication Type: Academic Journal

Source(s): Electromagnetic Biology & Medicine. 2022, Vol. 41 Issue 2, p230-255. 26p.

Abstract: In this paper, we review the literature on three important exposure metrics that are inadequately represented in most major radiofrequency radiation (RFR) exposure guidelines today: intensity, exposure duration, and signal modulation. Exposure intensit...
