Lettuce plants fumigated with elemental tritium accumulated tritium in the plant water as well as in the organic constituents. The conversion rate of elemental tritium to tritiated water varied from 0.5 nanocuries per minute per pot at the start to 0.8 nanocuries per minute per pot at the termination of the 24-day exposure to an air concentration of 5 nanocuries per liter. Based on the concentration of tritium in various plant tissues, foliar absorption was postulated as the route of plant contamination. The data indicated that an enzymatically facilitated conversion on the leaf or soil surface was the probable mechanism.
