Radiotherapy and Cardiovascular Disease Survival Risk in Non-Small Cell Lung Cancer: A Population-Based Study From the Surveillance, Epidemiology, and End Results Database. [PDF]

open access: yesCancer Med
ABSTRACT Background It is well known that radiotherapy increases the cardiovascular risk of cancer patients, but there are few large‐sample studies with cardiovasular‐specific death as the endpoint in lung cancer patients. Methods Patients aged ≥ 18 years diagnosed with non‐small cell lung cancer were retrospectively enrolled from the Surveillance ...

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The use of stable Cs and Sr as proxies for the estimation of radionuclide soil-plant transfer factors [PDF]

open access: yesЯдерна фізика та енергетика
Transfer factors are key inputs for modelling the transport of radionuclides in the environment and for assessment of risk to humans and wildlife. However, for many combinations of soil conditions, plant species (products), and radionuclides, such ...

Study of the detection efficiency of a surface contamination monitor according to the distance and the surface emission rate

open access: yesSaúde & Tecnologia, 2015
Introduction – A radioactive contamination needs to be quantified in case it eventually occurs. Therefore it is necessary to ensure that the operating conditions of a surface contamination monitor are characterized by determining its detection efficiency.

Anthropogenic radionuclides 137Cs and 90Sr in the southern Baltic Sea ecosystem

open access: yesOceanologia, 2013
The radioisotopes of caesium (137Cs) and strontium (90Sr) make the greatestcontribution to the radioactivity level due to artificial radionuclides in the BalticSea, where the level of 137Cs contamination is higher than in any otherpart of the world ocean.

Chelator‐Free Radiometal Labeling Inside Engineered Affibodies

open access: yesAngewandte Chemie, Volume 138, Issue 30, 20 July 2026.
Affibodies are compact and robust three‑helix binders used in imaging and therapy. Engineering a triple‑cysteine motif into their core enables chelator‑free binding of important radiometals, like Bi(III), Pb(II), In(III), and Ga(III) with rapid uptake and exceptional stability.

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

The Ames impact structure, Oklahoma: New radioisotopic constraints and implications for North American impact chronology

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The Ames impact structure (Oklahoma) is thought to have formed during the Ordovician Meteor Event, based on conodont biostratigraphy of its crater fill. Here, U–Pb zircon dates from its impact‐melt portion, conducted using secondary ion mass spectrometry and laser ablation–inductively coupled plasma–mass spectrometry (n = 37 spots), yield a ...

Brachytherapy in Breast Cancer Treatment: Physical and Biological Aspects

open access: yesJournal of Education, Health and Sport
This scientific paper focuses on the treatment of breast cancer, one of the most common cancers among women. Despite increased awareness and the popularity of screening tests, statistics indicate a significant rise in incidence.
