[Correlation between the biological half-life of tritiated water and the body surface area in man. Preliminary report].

The literature about the half-life of the tritiated water has shown a great variety from one specimen to another. In order to determine the influence of this variations upon metabolism, mass or body surface we studied 16 healthy subjects and one patient with renal failure. We founded that there is a good correlation between the body surface and the biological half-life of the tritiated water in humans. The correlation average was 1.02.
