ABSTRACT:
A method for producing229Th includes the steps of providing226Ra as a target material, and bombarding the target material with alpha particles, helium-3, or neutrons to form229Th. When neutrons are used, the neutrons preferably include an epithermal neutron flux of at least 1×1013n s−1·cm−2.228Ra can also be bombarded with thermal and/or energetic neutrons to result in a neutron capture reaction to form229Th. Using230Th as a target material,229Th can be formed using neutron, gamma ray, proton or deuteron bombardment.
