The Dosimetric Demise of 97MNB.

Radionuclide differences between ICRP Publication 38 and its succeeding work, ICPR Publication 107, are reviewed. The specific example of the isomer Nb is discussed, examining how dose reporting for this nuclide can be an issue.

Location Modification Factors for Potential Dose Estimation.

A U.S. Department of Energy facility must comply with the National Emission Standard for Hazardous Air Pollutants for radioactive air emissions.

Development of criteria used to establish a background environmental monitoring station.

It is generally considered necessary to measure concentrations of contaminants-of-concern at a background location when conducting atmospheric environmental surveillance. This is because it is recognized that measurements of background concentrations can enhance interpretation of environmental monitoring data. Despite the recognized need for background measurements, there is little published guidance available that describes how to identify an appropriate atmospheric background monitoring location.

The Livermore phantom history and supplementation.

In vivo monitoring facilities determine the absence or presence of internally entrained radionuclides. To be of greatest utility, the detection systems must detect and quantify the nuclides of interest at levels of interest. Phantoms have been developed to improve measurements at in vivo monitoring facilities.
