A comprehensive approach to age-dependent dosimetric modeling
Leggett, R.W.; Cristy, M.; Eckerman, K.F. - 2008
In the absence of age-specific biokinetic models, current retention models of the International Commission on Radiological Protection (ICRP) frequently are used as a point of departure for evaluation of exposures to the general population. These models were designed and intended for estimation...

Some computer simulations based on the linear relative risk model
Gilbert, E.S. - 2008
This report presents the results of computer simulations designed to evaluate and compare the performance of the likelihood ratio statistic and the score statistic for making inferences about the linear relative risk mode. The work was motivated by data on workers exposed to low doses of...

Foreign criteria and programs
Swinth, K.L.; Thompson, I.M.G. - 2008
The concept of measurement quality assurance (MQA) as embodied in National Institute of Standards and Technology (NIST) programs is not generally used within European programs for testing or accreditation. Although the essential elements of quality control and quality assurance are in the...

Two-stage sampling for acceptance testing
Atwood, C.L.; Bryan, M.F. - 2008
Sometimes a regulatory requirement or a quality-assurance procedure sets an allowed maximum on a confidence limit for a mean. If the sample mean of the measurements is below the allowed maximum, but the confidence limit is above it, a very widespread practice is to increase the sample size and...
