The useful life of a 99Mo - 99mTc generator is about 3 parent half lives, or approximately one week. How do we get Tc-99m from a cow? A technetium-99m

The technetium isotope 99mTc is unusual in that it has a half-life for gamma emission of 6.03 hours. This is extremely long for an electromagnetic decay - more typical is 10-16seconds. 99m Tc decays, in turn, to 99 Tc, with a half-life of 6.02 hours.

Tc 99m half life

Type of Radiation Emitted: Half-life Half-life The time required for half of the radioactive atoms present to decay or transform. The metastable technetium-99m (99m Tc) is a short-lived (half-life about 6 hours) nuclear isomer used in nuclear medicine, produced from molybdenum-99. It decays by isomeric transition to technetium-99, a desirable characteristic, since the very long half-life and type of decay of technetium-99 imposes little further radiation burden on the body. No beta particles emitted by Tc-99m . Specific Gamma Ray Constant 0.076 mrem/h at 1 meter per 1 mCi, or 760 mrem/h at 1 cm per 1 mCi Physical Half-Life 6.02 hours Biological Half-Life 24.00 hours Effective Half-Life 4.80 hours Specific Activity 5,243,820 curies/gram ("carrier free"/pure Tc-99m) 3.4 x 106 curies/gram (99m Tc-pertechnetate form) Technetium Tc 99m decays by isomeric transition with a physical half-life of 6.02 hours. 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. Technetium Tc 99m decays by isomeric transition with a physical half-life of 6.02 hours 2.

Due to their short decay times, Mo-99 and Tc-99m cannot be stockpiled and of other beta emitters with a half life longer than 5 years (e.g. C-14, Se-75. 2. Sum. 1170. Sr-90.

A steady supply of Mo-99m, which has a half-life of about three days, is needed to make enough technetium to meet world demand. Because Tc-99m’s radioactive half-life is just six hours, it must be made from Mo-99 at or near the place where the heart patients get their stress tests.

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. It has a short half-life (6 hours) and does not remain in the body or the environment for long.
