How is technetium obtained now?
The metal technetium has no stable isotopes. It is synthesized in the physics lab by lowering a molybdenum sample into an operating nuclear reactor. The molybdenum is bathed in the nuetron flux, and neutron capture will occur and transmute the molybdenum into technetium. The sample is then withdrawn and put into a shielded casket to make it available for use. A link is provided to the Wikipedia article on technetium.
