A simulated aerospace study was conducted to assess the biochemical effects of space flight by determining the volume of urine output of each crewman. The Apollo urine transport system UTS, using a radioisotope, tritium, dilution technique, was tested by four human male subjects. The Apollo UTS met minimum requirements for 14 days even when a single unit was used by four individuals. The best individual performance by a subject gave a ratio of 101.4 plus or minus 4.6. The overall value for volume measurement from the four subjects was 100.6 plus or minus 4.6. Any void volume may be calculated by this radioisotope method with the UTS system plus or minus 10 of its volume at the 95 confidence level. One experimental error was the incomplete mixing of the radiosotope. The practicability of this procedure in actual space missions still has to be determined. Author
