2. The hospital used a technetium isotope in a medical imaging procedure.
3. The engineer used a technetium tracer to determine the flow of water in the pipes.
4. The chemist was fascinated by the unique chemical properties of technetium.
5. The geologist discovered trace amounts of technetium in a mineral sample from the Earth's crust.
