Abstract
To make
in situ
identification of human physiological fluids by nuclear magnetism, we use the well known technique of free precession of water protons in the magnetic field of the Earth after prepolarization in a perpendicular (H
p
) field (Packard & Varian 1954). The central part of the apparatus is the coil used for generating the polarizing field (maximum values 50- 100 Oe (3979-7958 A m
-1
)) and detecting the free precession of nuclei. To make
in situ
measurements, the coil is placed against the corresponding part of the body; thus, to pick up signals from blood in the region of the heart, the coil is placed on the anterior part of the thorax; to detect urine in the bladder, the coil is placed against the ventral part of the low abdomen (Béné
et al
. 1977).
