TL;DR: A review in gold nanoparticles focusing on chemical reduction synthesis mechanisms is presented in this paper, where the most commonly used synthesis methods are: Turkevich Method, NaBH4 with/without citrate, Seeding-Growth, Synthesis by Ascorbic Acid, Green Synthesis, Brust-Schiffrin, and synthesis using other reducing agents.

TL;DR: This work aims to present and evaluate the radiological protection procedures applied to imported sources in order to assist in the setup of the new laboratory at the IPEN, and demonstrate that there is no area contamination and very low exposure.

TL;DR: Evaluated absorbed dose distributions in near-surface regions around Ir-192 HDR sources yields achievable measurements and with proper clinical technique and accessories should apply as an alternative for treatment of lesions where only beta sources were used.

TL;DR: A Monte Carlo-MCNP6 simulation was performed to evaluate the TG-43 parameters and points of importance were evaluated/discussed: photo-sensibility, reaction vial type, the substitution for iodine-131, pH, and solution volume.

TL;DR: The method allows almost quantitative deposition of iodine-131 on dozens of silver substrates at once, with even distribution of activity per core and insignificant amounts of liquid and solid radioactive wastes, allowing the fabrication of cheaper radioactive iodine seeds for brachytherapy.
