Tc
metal· Tc
Technetium (Tc) is a synthetic transition metal with no stable isotopes, produced artificially through nuclear fission or cyclotron bombardment. It is primarily used in medical imaging and nuclear medicine applications, where its radioactive isotopes (especially Tc-99m) serve as tracers for diagnostic procedures including bone scans, cardiac imaging, and infection detection. Engineers encounter technetium primarily in nuclear medicine instrumentation design, radiation shielding, and specialized catalyst applications in chemical processing, where its unique nuclear and chemical properties offer advantages unavailable from stable elements.

Regulatory Screening
Environmental
Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
