21. Technetium -99m was discovered as a product of cyclotron bombardment of molybdenum.22. The technetium -99m radioisotope is used predominantly in bone and brain scans. 23. ZVI has the potential to remove technetium in groundwater. 24. Last month's passenger flight carried radioactive technetium generators used in medical equipment. 25. Strand said levels of technetium remained low, and were not an immediate danger. 26. Two polymorphs of technetium trichloride exist, ?-and ?TcCl 3. 27. All isotopes of technetium must be handled carefully. 28. Nearly all technetium is produced synthetically and only minute amounts are found in nature. 29. Technetium is the primary isotope used in millions of nuclear cardiology procedures every year.30. Technetium bone scans can detect regional blood flow and the amount of osseous uptake.
