Spectra, yields, average energies, and kerma rates in tissue of neutrons from 21‐MeV deuteron bombardment of deuterium gas targets have been calculated for target thicknesses of 1, 3.5, and 5 MeV. A high pressure gas cell was constructed and was filled with 33 atm of D 2 gas (equivalent to an energy loss of 3.5 MeV for 21‐MeV deuterons); dose rate, dose buildup, and depth‐dose properties of neutrons produced by the D( d , n ) reaction were measured. Dosimetric properties of these neutrons are superior to those of neutrons from a thick Be target bombarded by a deuteron beam of the same energy.
