6.2 Producing the radioactive substance (elution)

In the radiopharmacy Tc-99m is produced in a generator.

Mo-99, a product of the fission of uranium, is isolated from a nuclear reactor and absorbed on to an alumina column in the generator. When a saline solution is passed over the column, ion exchange results in the production of sodium pertechnetate. This can then be chemically manipulated to form a variety of compounds. The removal of the technetium by the passage of saline is known as elution.

Conveniently, the optimum interva

A Primer on Natural Resources and the Environment

There is a fundamental fact about the world that has profound implications for the supply of natural resources and for the relationship between production and economic activity on the one side and man's environment on the other. This is the fact that the entire earth consists of solidly packed chemical elements. There is not a single cubic centimeter either on or within the earth that is not some chemical eleme

Arctic Tern Migration Google Earth Tour Video
The Arctic Tern (Sterna paradisaea) makes an incredible migration each year. These small birds travel distances of more than 50,000 miles, from pole to pole, crossing through temperate and tropical regions along the way. Carsten Egevang used geo-locator tags to track ten of these terns, and he shares their story with us in this tour.

Towards Comprehensive Space: A context for the programming/design of cybrids
Cybrids have been presented as mixed realities: spatial, architectural compositions comprised of physical and cyberspaces (Anders 1997). In order to create a rigorous approach to the design of architectural cybrids, this paper offers a model for programming their spaces. Other than accepting cyberspaces as part of architecture?s domain, this approach is not radical. Indeed, many parts of program development resemble those of conventional practice. However, the proposition that cyberspaces should

Spatial and Temporal Sequence: Film, animation and design theory - toward a constructed morphology
This paper presents an investigation of film, space, form and motion to expose issues of spatial perception. The objective is to use a brief moment of constructed moving imagery (a film scene) as the vehicle to develop a spatial/temporal sequence. The design research focuses on an examination of the procedure or process constructed by the director/cinematographer. The changing position of the camera continually changes the relationship of the frame to the viewed context. The project asks the stu
