There are 39 known isotopes and 17 nuclear isomers of tellurium (52 Te), with atomic masses that range from 104 to 142. These are listed in the table below. Naturally-occurring tellurium on Earth consists of eight isotopes. Two of these have been found to be radioactive: 128 Te and 130 Te undergo double beta decay with half-lives of, respectively, 2.2×10 24 (2.2 septillion) years (the longest ...
The other two, 128 Te and 130 Te, are slightly radioactive, [17] [18] [19] with extremely long half-lives, including 2.2 × 10 24 years for 128 Te. This is the longest known half-life among all radionuclides [20] and is about 160 trillion (10 12) times the age of the known universe.

Iodine-128 (half-life 25 minutes) can decay to either tellurium-128 by electron capture or to xenon-128 by beta decay. It has a specific radioactivity of 2.177 × 10 6 TBq/g . Nonradioactive iodide ( 127 I) as protection from unwanted radioiodine uptake by the thyroid
The telluride iodides are chemical compounds that contain both telluride ions (Te 2 ... C2/c: a = 16.199 b = 8.128 c = 27.355 β = 110.84°, Z = 4 black metallic [9]
2 CH 3 I + Na 2 Te → (CH 3) 2 Te + 2 NaI. Dimethyl telluride is formed by the body when tellurium is ingested. Such compounds are often called telluroethers because they are structurally related to ethers with tellurium replacing oxygen, although the length of the C–Te bond is much longer than a C–O bond. C–Te–C angles tend to be ...
