Folding model analysis of alpha radioactivity

open access: yes, 2002
Radioactive decay of nuclei via emission of $\alpha$ particles has been studied theoretically in the framework of a superasymmetric fission model using the double folding (DF) procedure for obtaining the $\alpha$-nucleus interaction potential.

Digitonin‐Loaded Nanoscale Metal–Organic Framework for Mitochondria‐Targeted Radiotherapy‐Radiodynamic Therapy and Disulfidptosis

open access: yesAdvanced Materials, EarlyView.
A mitochondria‐targeted cationic nanoscale metal organic framework shows strong radiotherapy‐radiodynamic therapy effects and selectively releases digitonin in acidic tumor microenvironments to induce disulfidptosis of cancer cells and downregulate immune checkpoints in cancer and T cells, thereby eliciting strong antitumor immunity to effectively ...

Exact method for determining subsurface radioactivity depth profiles from gamma spectroscopy measurements [PDF]

open access: yesarXiv, 2011
Subsurface radioactivity may be due to transport of radionuclides from a contaminated surface into the solid volume, as occurs for radioactive fallout deposited on soil, or from fast neutron activation of a solid volume, as occurs in concrete blocks used for radiation shielding.

Radioactivity Measurements of the Jos Tin Mine Tailing in Northern Nigeria [PDF]

open access: yes, 2011
The activity concentrations of 226Ra and232Th in Jos Tin mine tailings and its environment were measured using Hyper-pure Germanium detector (HPGe). Preset counting time of 30,000s was used for each sample to avoid statistical errors.

Progress and Application of Multifunctional Hydrogel in Radioactive Skin Injury

open access: yesAdvanced Materials Interfaces, EarlyView.
This review examines healing challenges in radiation‐wound injuries, where ionizing radiation impairs immune and tissue repair processes. Hydrogels, with their biocompatibility, antimicrobial properties, and drug delivery capabilities, present a transformative solution. It compares hydrogel efficacy in radiation‐induced versus common wounds, highlights

Nanohybrid of Silver‐MXene: A Promising Sorbent for Iodine Gas Capture from Nuclear Waste

open access: yesAdvanced Materials Interfaces, EarlyView.
Silver‐MXene (Ag‐Ti3C2Tx) nanohybrids effectively captured iodine gas at 150 °C, with Ag nanoparticles loaded onto MXene via silver nitrate reduction. Upon exposure to iodine gas, silver iodide forms, confirming successful adsorption. Ag‐Ti3C2Tx shows superior iodine uptake (946 mg g−1) compared to conventional sorbents, demonstrating its potential as ...
