Investigation of tubal infertility by radionuclide migration

Human Reproduction, 1991
Investigation of the tubal factor in infertility is limited to an assessment of anatomical structure and tubal patency. No test of ascendant tubal function is currently available. The migration of radionuclide (99mTc-labelled human albumin microspheres) through the genital tract in 96 infertile women was compared with pelvic findings at laparoscopy and

Migration of Radionuclides in Fracture Columns

MRS Proceedings, 1990
ABSTRACTRadionuclides transported by ground water flowing through fractures may be delayed by interactions with the fracture surfaces. The migration of radionuclides in fractures was studied under well defined laboratory conditions using tonal-ite drill core columns with a fracture running parallel to the core axis. The hydrodynamic characterization of

CHERNOBYL RADIONUCLIDE DISTRIBUTION AND MIGRATION

Health Physics, 2007
The accident at Unit No. 4 of the Chernobyl Nuclear Power Plant on 26 April 1986 presented severe challenges in radiation protection. Early activity measurements defined the contaminated areas in order to determine what persons should be evacuated on the basis of the exposure limit at that time of 100 mSv (10 rem) for accidents.

Radionuclide Migration Studies on Tonalite

MRS Proceedings, 1992
ABSTRACTMigration of water, chloride, sodium, and calcium in tonalite was studied, using dynamic column and static through-diffusion methods. Autoradiography of rocks impregnated with 14C-methylmethacrylate was introduced in order to determine the spatial porosity distribution, as well as to identify and visualize the migration pathways of non-sorbing ...

On the Rate of Radionuclide Migration in Groundwater

Water Resources, 2002
Analytical and numerical modeling is used to demonstrate that it is possible in principle for radionuclides in small concentrations to migrate through groundwater with the velocity of water flow. This effect is due to the presence of Clarke concentrations of the respective stable isotopes in the water-bearing rocks.

Migration of radionuclides in the enviroment

Journal of Radioanalytical and Nuclear Chemistry, 1998
The mechanisms of transport and retaidation processes, chemistry and migration behaviour of radionuclides of fission products and actinides in engineered barriers, especially bentonites, have been summarised. A “critical group of radionuclides” is proposed for thorough investigation of their retardation properties in natural sorbents. The evaluation of
