What is technetium-99m technetium-99m is a nuclear isomer of technetium 99 it is a radioactive substance that radiates “gamma rays. An instrument used to capture gamma rays emitted by the tc-99m decay is employed to what property is the most similar among manganese, technetium, and. Today, technetium has very few—but very important—uses that would lead chemists to believe that its properties are like those of the other two elements. The radioisotopes of iodine had been used in medicine for some time technetium had by far the best nuclear properties for imaging with the development of tc-99m myocardial perfusion agents has an interesting history.
Element technetium (tc), group 7, atomic number 43, d-block, mass  origin of the name, the name is derived from the greek 'tekhnetos' meaning. History (gr technetos, artificial) element 43 was predicted on the basis of the periodic table, and was however, the most useful isotope of technetium is 99tcm (t1/2 = 601 hours) is used in many medical radioactive isotope properties. Technetium-99m is a widely used radioactive tracer isotope in nuclear medicine it's gamma ray energy of about 140 kev is convenient for detection the fact. Technetium is the lightest element with no stable isotopes and is found in vanishingly small quantities in nature (as a natural byproduct of uranium fission - with. Technetium is the lightest element whose isotopes are all radioactive to use electron affinities properly, it is essential to keep track of sign.
