Use of activated carbon in removal of some radioisotopes from their waste solutions

Journal of Hazardous Materials, 2008
Removal of some radioisotopes namely (152+154)Eu and (65)Zn from radioactive solutions by activated carbon using both batch and column techniques has been performed. Experimental studies were conducted to evaluate and optimize the various process variables, i.e., equilibrium time, carbon dose, solution pH.

Highly porous carbon-SiC composites with continuous carbon fibers for the production of radioisotopes in ISOL facilities

Journal of the European Ceramic Society
New C/SiC composites with continuous fibers were produced through impregnation of carbon fiber preforms and consolidation by hot pressing. The resulting sintered material was investigated as a potential target for nuclear applications, such as radioisotope production.

Recording micro-densitometer employing beta-radiation from a carbon-14 radioisotope source

British Journal of Applied Physics, 1961
The variation of wood density through the thickness of the individual growth rings of trees is of interest to those concerned with research on the growing of trees and the subsequent utilization of the timber. An experimental instrument has been developed in which a finely collimated beam of carbon-14 beta-particles is used to measure the density ...

A radioisotope method for locating points of entry of carbon monoxide into the cabin of an aircraft

The International Journal of Applied Radiation and Isotopes, 1966
Abstract The point of entry carbon monoxide exhaust gas into the cabin of a light aircraft during flight has been identified by a radioisotope technique. Krypton-85 gas was into the aircraft engine and the cabin monitored with a plastic phosphor detector.

Investigation of the carbon dioxide distribution in cement bound wood samples using the radioisotope tracer technique

International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1992
Abstract Cement bound wood bricks are widely used as building element for light construction buildings. Static characteristics of bricks can be considerably improved by treating the raw mixture of cement-wood-water with carbon dioxide during the bonding process. Distribution of the CO2 among components and within the components is an important factor

Sodium VCHP with Carbon-Carbon Radiator for Radioisotope Stirling Systems

AIP Conference Proceedings, 2010
In a Stirling radioisotope system, heat must continually be removed from the General Purpose Heat Source (GPHS) modules to maintain the modules and surrounding insulation at acceptable temperatures. The Stirling converter normally provides this cooling.
