I am working on a Monte Carlo simulation of a medical linear accelerator (LINAC) using MCNP5. My objective is to calculate the radiation dose at the isocenter of the LINAC treatment setup. I have constructed the LINAC geometry, including the relevant components of the treatment head, and... Read more
IntroductionLow-dose computed tomography (CT) scans can induce DNA damage, including chromosomal aberrations (CAs) and DNA double-strand breaks, which may contribute to long-term cancer risk. D-limonene, a bioactive component present in several Kampo formulas, has shown radioprotective effects in preclinical studies; however, clinical evidence remains limited, and the gastrointestinal side effect…
Delayed effects of acute radiation exposure (DEARE), including radiation pneumonitis (lung-DEARE), develop weeks to months after radiation exposure. Pathway-targeted biomarkers that capture early oxidative stress and cell death could improve risk stratification and provide objective measures of mitigator efficacy. The objective was to test whether molecular lung imaging predicts long-term surviva…
Something remarkable in radioprotective treatments comes from an unlikely source—frog skin. Researchers led by Professor Shuyu Zhang from Sichuan University, Professor Jie Zhang from Fourth Military Medical University, Professor Jianping Cao from Soochow University and colleagues have identified a substance derived from the skin of frogs that offers substantial protection against radiation-induce…
Researchers from the University of South Carolina in Columbia used satellite imagery of fires in the 2000s and field measurements of radioisotope levels to model changes in the distribution of radiation over the region. The researchers found that fires likely spread radiation across much of Eastern Europe, with Ukraine, Belarus and Russia receiving the highest doses. Traces of radioactive cesium-…
