✦ Synopsis

In quantitative analyses of dynamic radionuclide studies, using large activities of 99mTC flowing through organs it is necessary to determine accurately count-rate losses and to provide appropriate corrections.

A method is described for estimating deadtimes and applying corrections to the observed counting rates using a two component model where the gamma camera is considered to have a purely paralyzable deadtime and the data analysis system a purely nonparalyzable deadtime.

## Abstract Adaptive bias corrections for satellite radiances need to separate the observation bias from the systematic errors in the background in order to prevent the analysis from drifting towards its own climate.
