Airborne Exhalation of Radioactivity from Animals Injected with Radioactive Substances.

RADIOISOTOPES, 1996
Few reports were published on exhalation of a radioactive substance into the air from animals injected with it. For safe handling of iodine-125 in research using animals, we examined daily changes of airborne release of radioactivity from housing cages, containing mice treated with Na 125I or 125I labelled anti-mouse monoclonal IgG1κ.

Modelling of hydrodynamic and solute transport with consideration of the release of low-level radioactive substances

Safety of Nuclear Waste Disposal, 2021
. When nuclear power plants are dismantled, only a small portion is heavily contaminated with radioactivity and must be stored in a repository. The remaining material, mainly concrete rubble (construction waste), is decontaminated if necessary and can be

Metabolic Study of Tetra-PEG-Based Hydrogel after Pelvic Implantation in Rats

Molecules, 2022
In vivo metabolism of polyethylene glycol (PEG) hydrogels has rarely been studied. In this study, we prepared a chemically crosslinked hydrogel formulation using 14C-labeled tetra-armed poly (ethylene glycol) succinimidyl succinate (Tetra-PEG-SS) and 3H ...
