Lawrence Dietlein, assistant director for life sciences at NASA's Johnson Space Center, Houston, said that in 1963 and 1974 the Center conducted experiments involving the use of very small doses of radiation on humans. The experiments, done with the consent of the subjects, concerned bone loss and weightlessness during space flight. (Reuters, Feb 17/94; W Times, Feb 18/94; USA Today, Feb 18/94)
