An Evaluation of Whole Body Potassium-40 Content for Estimating Lean and Fat Mass in Pigeons’

A severe limitation in studies of avian ecological energetics is the lack of an accurate, noninvasive technique for determining whole body fat storage in living birds. We explored a technique of assaying total body potassium as a predictor of lean mass (LM) and then derived fat mass (FM) by subtracting LM from total body mass. Body potassium ’ Received 15 December 1997. Accepted 3 April 1998. (...

Whole body counting in erythrocyte survival studies.

In Cancer Research, 26: 198-201, Feb. 1966, Brodsky et at. describe a method for determining the red cell survival in mice, based on whole-body counting after injection of 51Cr-labeled red cells. Inspired by this article, we decided to use the method which seemed to have some obvious advantages over the sampling method. Three hundred /L1. of red cells, labeled with 1 uc. 51Cr ( specific activit...

Whole Body Counting in the Iaea Laboratory

Among the current activities of the IAEA laboratory is a project for the measurement and analysis of small amounts of radioactivity in living persons. This is done with what is known as a "whole body counter" installed in the basement of the Agency's headquarters building in Vienna. This facility is also available for rendering services to Member States at their request as part of the bio-assay...
