National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Predicting Worker Exposure from a Glovebox Leak.

DE2001781642

Publication Date	2001
Personal Author	Jordan, H.; Gordon, D. J.; Wicker, J. J.; Wannigman, D. L.
Page Count	36
Abstract	In this report, we present such a means in the form of a simple calculation model that is easily applied and generates reasonable, qualitative dose predictions. The model contains a scaling parameter whose value was deduced from extensive laboratory ventilation flow rate measurements performed at Los Alamos National Laboratory (LANL) over the last several years and from recent indoor radioactive contamination dispersion measurements, also at LANL. Application of the model is illustrated with the aid of two example calculations. Predicting immediate worker radiological consequences from a hypothetical airborne leak from a glovebox is difficult. This difficulty is recognized in DOE safety analysis guidance in general and the reason that such guidance does not call for quantitative determinations of immediate worker consequences from postulated accidents. In contradistinction, however, DOE safety analysis guidance provides specific approaches to evaluating consequences to an offsite individual. The reason that worker consequences from such events are difficult to predict is that their phenomenology is impossible to define (predict) to the precision required. This situation arises from the fact that both the distance from source to the receptor and the duration of exposure are short. Uncertainties in the location of the worker (relative to the source) and the duration of exposure are therefore large fractions of their respective absolute values.
