Abstract
Low-temperature autoradiography, already described by one of the authors, has been applied to the study of the diffusion of tritiated water in the animal organism. In the course of this work some striking disagreements were observed between the measured radioactivity of water in the organs and the relative intensity of blackening of the photographic plate on which they are projected. The cause of these paradoxical images was found in a phenomenon of luminescence, induced by the very soft beta. The application of the low-temperature autoradiography technique to the detection of tritium beta rays therefore involves the use of filters opaque to ultraviolet and visible light, but permitting the autoradiographic recording of radioactivity.
