The principal photon that is useful for detection and imaging studies is listed in Table 1. Reference ID: 3019372Reference ID: 3019508 . 1 Tc-99m is not a concern at these sites because of its short half-life. Tc-99 is also found in the radioactive waste of nuclear reactors, fuel cycle facilities, and hospitals. In the natural environment, Tc-99 is found at very low concentrations In air, sea water, soils, plants, and animals. The behavior of Tc-99 in soils depends on many factors.

All technetium isotopes are radioactive. Technetium 99m (m=metastable) which is the decay product of Molybdenum 99, has a half-life of about 6 hours and is

4 × 100. 1 × 102.

Technetium (99mTc) exametazime is a radiopharmaceutical sold under the trade name Ceretec, and is used by nuclear medicine physicians for the detection of

Blood clearance studies indicate that the fast clearing component clears with a t½ of 4.3 minutes at rest, and clears with a t½ of 1.6 minutes under exercise conditions. A relatively short physical half-life of six hours, and a biological half-life of one day, makes Tc-99m ideal for use in procedures such as single-photon emission computed tomography (SPECT). Importantly, soon after the procedure ends, no radioactivity is left in the body. a) Tc 99m decays by isomeric transition with a physical half-life of 6.02 hours. The principal photon that is useful for detection and imaging studies has a percent Technetium-99m is a short-lived form of Tc-99 that is used as a medical diagnostic tool.

The metastable isotope technetium-99m (6-hour half-life), used with radiographic scanning devices, is valuable for studying the anatomic structure of organs.
