The Scintillation of Stars [PDF]
Nature, 1950 IN a recent communication in Nature1, Dr. A. H. R. Goldie has suggested that the scintillation of stars may be associated with waves at an interface between two currents of air which have a difference of temperature of the order of 5–7° F. “Such waves,” he writes, “should not uncommonly have an amplitude of the order of up to 500–1,000 ft.

Radioactive contamination of scintillators [PDF]
International Journal of Modern Physics A Vol. 33, No. 9 (2018)
1843007 (42 pages), 2018 Low counting experiments (search for double $\beta$ decay and dark matter particles, measurements of neutrino fluxes from different sources, search for hypothetical nuclear and subnuclear processes, low background $\alpha$, $\beta$, $\gamma$ spectrometry) require extremely low background of a detector.

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract Purpose The aim of this work was to evaluate the SunCHECK PerFRACTION, the software for in vivo monitoring using EPID images. Materials/Methods First, the PerFRACTION ability to detect errors was investigated simulating two situations: (1) variation of LINAC output and (2) variation of the phantom thickness.
