Both Lutetium Isotopes are generally considered to be stable, although strictly speaking Lu-176 is not entirely stable with a half-life of 3.78 x 1010 years. Lu-175 can be used as a yield tracer in the ICP-MS based determination of Pu in urine. Lu-176 is used for the production of “Carrier added” Lu-177 which is a very promising radio-immunotherapy isotope for the treatment of small, soft tumors.

Ytterbium has seven stable isotopes and two of them are used for medical and industrial purposes. Yb-168 is used for the production of Yb-169 and this radioisotope is used as a radiation source in gamma cameras. Yb-169 is also used in the medical field where it has been proposed as an alternative for I-125 and Pd-103 in the treatment of prostate cancer while it is also used for diagnostics in the gastrointestinal tract. Yb-176 can be used as a target for the production of carrier-free Lu-177 with a high specific activity. Yb-171 in an excited state has been proposed as an optical frequency standard, while the other Yb isotopes are used in various physics experiments.

Gadolinium Isotopes have the highest cross section for the capture of thermal neutrons of any element and this is mainly due to the high cross section of Gd-157 (255,000 barn) and Gd-155 (61,000 barn). Natural Gadolinium is currently used as a burnable poison in nuclear fuel, but the use of Gd-155/157 only has been proposed as this would create an even more effective burnable poison. Gd-152 is used for the production of radioactive Gd-153 which is used for osteoporosis research and bone density measurements. Gd-160 is used in double beta decay research and for the production of the mecdical isotope Tb-161.

Thallium has two stable isotopes and one of these, Tl-203, is used to produce one of the “workhorses” of nuclear medicine: Tl-201. Tl-201 is used extensively for imaging and in particular for perfusion tests of the myocardium. These tests are done to determine the damage to the heart from a heart attack or from heart diseases. Tl-205 has been proposed as an alternative target for the production of Tl-201. Tl-205 is also used in nuclear magnetic resonance research.

Mercury Isotopes are mainly used in the study of the deposition and emission of Hg in both terrestrial and aquatic ecosystems. In one experiment in Canada three different Mercury isotopes (Hg-198, Hg-200 and Hg-202) were used to find out how the route of entry of mercury to an ecosystem affects the amount that becomes accumulated in fish. Several other trials using Hg isotopes are, or have been, undertaken in lakes in the US and Canada. Hg-202 is also used for the production of radioactive Hg-203 which is used for gamma radiation calibration.

Both Iridium Isotopes, Ir-191 and Ir-193 are used in the production of radioactive material. Ir-191 is used for the production of radioactive Ir-192. This Ir-192 is used as a radiation source in gamma cameras that are used for non-destructive testing. Ir-192 sources are also used in so-called brachytherapy procedures whereby radioactive materials are placed in close contact with the tissue being treated. Although Ir-192 can be produced from natural Ir, the use of enriched Ir-191 gives a much higher specific activity and allows the use of smaller sources. The use of Ir-193 has been suggested for the production of the therapeutic radioisotope Pt-195m.

Tantalum has only two isotopes and one of them, Ta-180, has one of the lowest natural abundances of all naturally occurring isotopes (0.012%). Ta-180 has only been produced in minute quantities and is very expensive. Ta-181 can be used for the production of W-178 which decays to Ta-178. Ta-178 emits low energy gamma rays which can be used for imaging purposes.

Of the nine stable Xenon Isotopes, several are used in various medical and scientific applications. Xe-124 is used in the production of two radioisotopes: I-123 and I-125. I-123 is used extensively in diagnostic procedures while I-125 is used in the treatment of prostate cancer. Hyperpolarized Xe-129 is used in the magnetic resonance imaging of gas flows in the lungs. Xe-136 has been proposed as a detector for neutrinoless double Beta decay research. Xe-126 can be used as a target for the production of radioactive Ba-128.

Tellurium has eight stable isotopes (Te-120 and Te-123 are usually considered stable because of their long half lives) and many of them have a medical application. Te-120 is used for the production of I-120g which has an application as a PET and Beta emitting isotope. Te-122 is used in the production of the radioisotope I-122 which is used in gamma imaging. Te-123 is used for the production of radioactive I-123 which is used in thyroid imaging. Te-124 is used for the production of both I-123 and the PET isotope I-124. Finally, Te-130 is used in the research into double Beta decay.

Two Antimony Isotopes are used for the production of medical radioisotopes. Sb-121 can be used for the production of I-124, although this medical radioisotope is usually produced via Te-124. Sb-121 and Sb-123 can both be used for the production of I-123, although the most common production route is via Xe-124 or Te-123.

The nine stable Cadmium Isotopes are used for many different purposes. Cd-110 is used for the production of the radioisotope In-110, while Cd-112 is used in the production of the widely used diagnostic radioisotope In-111. Cd-108 is used in the production of Cd-109 which is a calibration source for 88 keV gamma radiation. The even numbered Cadmium Isotopes (mainly Cd-110, Cd-112, Cd-114 and Cd-116) are used to improve the power output and coherence length of HeCd lasers.

Silver Isotopes Ag-107 and Ag-109 are used and have been proposed as precursor for the production of a number of radioisotopes. Ag-107 has been proposed for the (cyclotron) production of Pd-103, although the most common route for Pd-103 is via Rh-103 or Pd-104. Ag-109 is used for the production of Ag-110m which is used as a gamma reference source. Ag-109 can also be used for the production of In-110 (a replacement for the more commonly used In-111) and for the production of Cd-109, an 88 keV gamma reference source.

Palladium Isotopes are used in a variety of scientific applications. Pd-104 is used for the production of radioactive Pd-103 seeds which are used to fight prostate cancer. Pd-103 can also be made from Pd-102. Other Pd isotopes such as Pd-110 and Pd-108 have been used in physical experiments such as research into the decay of Nd-137 and nuclear fusion phenomena. Pd-108 can also be used for the production of radioactive Pd-109 which is used for cancer therapy.

Molybdenum Isotopes have several applications. Mo-95 is used for the production of the medical radioisotope Ru-97. Mo-96 is used for the production of the radioisotopes Tc-96 and Tc-95m, both of which have a medical application. Most Mo isotopes are also used in nutrition studies in humans. Depleted Mo-95 has been suggested for use in UMo fuel elements for materials test (high flux) reactors. Mo 100 is currently very in high demand.
