A unique tumor targeted method, which may be able to deliver a molecule to the surface of a tumor cell using the pH gradient between hypoxic tumor cells and normal tissue has recently been developed. Since solid tumors have been found to have a lower extra cellular pH compared to...
Biosphere models predict the transport of radionuclides in the environment with an end goal of assessing the possible risk to humans. Little data exists to support these mathematical biosphere models. The objectives of this work were to verify foliar uptake in biosphere models using experimental data, compare existing biosphere models...
The Self-indicating Instant Radiation Alert Dosimeter, SIRAD™,
manufactured by JP Labs*, is a dosimeter that can be used by emergency response
persoimel. It is a user-friendly, inexpensive, and disposable radiation dosimeter. It
monitors high doses, 5-200 rads, of ionizing radiation. The card resembles the size of a
credit card and...
Soil that is contaminated with radioactive elements poses an exposure hazard to those whom may take up temporary or permanent residence on such a site. Of particular interest is the internal exposure from ingestion of this radioactive soil. Although most ingestion of soil is inadvertent, usually being attached to foodstuffs...
An experimental environmental uptake model was developed for the purpose
of estimating the final harvest concentration of contaminant following an acute
accidental release of radiocesium onto an eastern Oregon winter wheat crop. The
system was developed using the PATHWAY environmental uptake model as
presented by Whicker and Kirchner (1987) for...
The Self-indicating Instant Radiation Dosimeter (SIRAD) is credit card size, self reading, single use dosimeter produced by JP Laboratories. The SIRAD has a chemical strip that changes color based upon incident radiation. The color change is instantaneous and cumulative. The card was designed for first responders as a way for...
As a standard practice, the use of radioactive materials has been widely used when treating many diseases. In recent years advances in biotechnology and labeling techniques have broadened the application of these materials. Candidates selected for radiopharmaceutical therapy may be treated on an outpatient basis or hospitalized following administration to...

As a standard practice, the use of radioactive materials has been widely
The photoneutron production from three Varian linear accelerators ranging in energies from 6 MV to 23 MV has been investigated. Photoneutrons are produced during (γ, n) interactions with materials located within the treatment head. These unwanted neutrons not only increase patient dose, but may also lead to the requirement of...
