Identifying the Presence of Natural Radionuclides in Ashlar Samples
Civil and Environmental Engineering, 2021 Humans have always been exposed to different types of natural and cosmic radiation. At present we experience 83 % natural radiation, for example from granite marbles, building materials such as concrete, brick, granite, or drywall.

Development of a real-time mobile gamma-ray measurement system for shipboard use
Nuclear Engineering and Technology, 2023 Large areas must be rapidly screened to monitor radiation in marine environments. For this purpose, this study developed a mobile real-time gamma-ray measurement system for shipboard use and evaluated its performance.

Effect of an extract of Centella asiatica on the biodistribution of sodium pertechnetate (Na99mTcO4) and on the fixation of radioactivity on blood constituents [PDF]
, 2008 This study evaluates the effects of an acute treatment with a Centella asiatica (CA) extract on the biodistribution of the radiopharmaceutical Na99mTcO4 and on the fixation of technetium-99m on blood constituents. Wistar rats were treated with CA extract

Time changes of dose equivalent rate above the soil surface as indication of natural attenuation processes [PDF]
Proceedings of the International Association of Hydrological Sciences, 2019 Eight sites in the Fukushima contaminated area were surveyed for long-term changes in D-shuttle dose equivalent rate above the soil surface during 2015–2017. D-shuttle readings in most cases decreased faster than if due to radioactive decay only.

The neglected activation of tantalum in reduced activation materials
Nuclear Materials and Energy, 2023 Due to the expression of “reduced activation”, the severe radioactivity of tantalum (Ta) after neutron irradiation in early decay years is easily neglected. In the presented study, after an irradiation of only 0.3 dpa by fission neutron and followed by a
