This invention relates to a process and apparatus for growing agricultural products with a reduced abundance of radioactive carbon-14 (.sup.14C) by employing centrifugal separation of atmospheric gases to selectively remove carbon dioxide (CO.sub.2) with .sup.14C. Agricultural products with reduced .sup.14C content can be grown in controlled environments with filtered atmospheric gases for the benefit of reducing harmful damage to human DNA that is unavoidable with our current food chain, due to the natural abundance of .sup.14C in atmospheric gases. Bilateral and unilateral compression helikon vortex apparatus provide efficient and economical removal of CO.sub.2 with .sup.14C from atmospheric gases with a single filtration pass, which is ideally suited for large scale agricultural production.

A new column-based purification system and approach are described for rapid separation and purification of the alpha-emitting therapeutic radioisotope .sup.211At from dissolved cyclotron targets that provide highly reproducible product results with excellent .sup.211At species distributions and high antibody labeling yields compared with prior art manual extraction results of the prior art that can be expected to enable enhanced production of purified .sup.211At isotope products suitable for therapeutic medical applications such as treatment of cancer in human patients.
