The application of radionuclide ventriculography to cardiac screening [PDF]

Clinical Cardiology, 1989
AbstractScreening asymptomatic individuals for latent coronary disease often requires sequential testing because exercise electrocardiography typically produces more false positive than true positive results in a population with a low prevalence of coronary disease. Cardiac scintigraphy is a technique that may be employed as a confirmatory test in lieu

Occurrence Probability of Large Solar Energetic Particle Events: Assessment from Data on Cosmogenic Radionuclides in Lunar Rocks [PDF]

Solar Phys., 289, 211-220 (2014), 2013
We revisited assessments of the occurrence probability distribution of large events in solar energetic particles (SEP), based on measurements of cosmogenic radionuclides in lunar rocks. We present a combined cumulative occurrence probability distribution of SEP events based on three time scales: directly measured SEP fluences for the last 60 years ...

A perspective from extinct radionuclides on a Young Stellar Object: The Sun and its accretion disk [PDF]

Annual Review of Earth and Planetary Sciences (2011) 39: 351-386, 2011
Meteorites, which are remnants of solar system formation, provide a direct glimpse into the dynamics and evolution of a young stellar object (YSO), namely our Sun. Much of our knowledge about the astrophysical context of the birth of the Sun, the chronology of planetary growth from micrometer-sized dust to terrestrial planets, and the activity of the ...

In-situ quantification of gamma-ray and beta-only emitting radionuclides [PDF]

arXiv, 2023
The prompt and in-situ assessment of non-gamma ray emitting radionuclides such as Sr-90 remains an outstanding challenge, particularly in radiological emergency response and consequence management situations. We have developed a new concept to quantitatively assess a wide range of radionuclides, including beta-only emitters, using coplanar-grid CdZnTe ...
