Introduction: In recent years, the use of neutrons has increased in various fields such as medicine and industry. One of the important applications of neutrons is in medical research. Neutrons have greater linear energy transfer than gamma rays and are considered more dangerous radiation. Hence, the detection and determination of neutron dose is a very important and vital issu...

Small particles of gold foil detached from an indoor decoration might be important evidence to associate a suspect with a crime scene. We have investigated the application of elemental analysis using synchrotron radiation X-ray fluorescence spectrometry to discriminate small particles of gold foil. Eight kinds of gold foil samples collected in Japan were used in the experiments. As a result of ...

Gold foil is the most underused restorative material in dentistry, and contrary to popular belief, it is still being used in many dental practices. As demonstrated, it can be used more easily than years ago and give the patient a restoration that may last a lifetime. Reasons for not using it have been addressed, and a simplified method of restoration has been explained in detail. It is the hope...

The scattering of α-particles off of gold foil was investigated. Attenuation of the α-particle beam was used to measure the thickness of the gold foil used. The coefficient of the Rutherford differential scattering cross section was experimentally determined to be (7.81 ± 5.35) × 10−25cm2, compared to 1.76 × 10−24cm2, with a reduced chi-squared of 3.4, which is a reasonable fit and confirms the...

Abstract: The timely detection of gold foil damage in gold-overlaid stone carvings and the associated maintenance of these relics pose several challenges to both the research and heritage protection communities internationally. This paper presents a new method for detecting gold foil damage by making use of multi-temporal 3D LiDAR point clouds. By analyzing the errors involved in the detection ...
