The intracorporal deposition of radon decay products was determined on four persons after 40 and 30 min respectively in radon water with about 1500 Bq/L by whole-body gamma spectrometry. The measurements started about 21/2 h after exposure. In addition, the radon activity concentration of inspiratory and expiratory air was measured on another person. The radon activity leaving the body with the expiratory air during exposure in the water (called "radon transfer") amounts to about 800 Bq. An intracorporal radon activity immediately after therapeutic exposure of about 3000 Bq was obtained as a result of first measurements by extrapolation from measurements starting about 2 1/2 hours later. Additional studies are necessary. There are indications that both the radon transfer and the intracorporal deposition can be increased by exposure in mixed radon-CO2 water.
