Verification of the applicability of the RAD7 radon monitor to the solid radon source exhalation reference model

Nuclear Engineering and Technology
The RAD7 radon monitor, based on the electrostatic collection method, is sensitive to humidity during measurements, necessitating the use of a desiccant to maintain the relative humidity in its built-in chamber less than 10 %.

Using Radiogenic Noble Gas Nuclides to Identify and Characterize Rock Fracturing

Earth and Space Science, Volume 12, Issue 1, January 2025.
Abstract Fracture‐released radiogenic noble gas nuclides are used to identify locations and constrain the volume of new fracture creation during subsurface detonations. Real‐time, in situ noble gases and reactive gases were monitored using a field‐deployed mass spectrometer and automated sampling system in a multilevel borehole array.

Effects of some physical conditions on leaching rate of radon from radioactive minerals originating from some hot springs [PDF]

, 2007
In order to determine the best physical conditions for leaching more radon from minerals into water, we measured the leaching rate of radon from radioactive minerals under the conditions of some different grain sizes and water temperatures.

A Novel Machine and Deep Learning–Based Ensemble Techniques for Automatic Lung Cancer Detection

BioMed Research International, Volume 2025, Issue 1, 2025.
Lung cancer (LC) remains one of the most challenging malignancies to diagnose accurately due to the complexity of its pathology and the limitations of traditional diagnostic protocols. This study presents a novel deep learning–based ensemble technique aimed at enhancing the automatic detection of LC, integrating machine learning (ML) methodologies to ...
