Overall this year, there has been some unsteadiness in the supply chain for Moly Mo , which in turn affects the supply of technetiumm Tcm. For operators of gamma cameras, availability of the radiopharmaceutical gives cause for concern. To understand why the supply chain is so sensitive, it helps to understand the Tcm production process. It is produced as a decay product of Mo Mo does not exist in nature but is most-often created using a nuclear reactor. It is developed by either fissioning uranium targets or bombarding non-radioactive molybdenum targets with neutrons.
The isotopes of Mo and technetiumm have short half-lives — 66 hours for Mo and just 6 hours for Tcm. This means they must be produced continuously and cannot be stockpiled. As a result, whatever is happening at the reactor can impact the Mo and technetiumm supply.
Anything that might prevent the production of Mo can very quickly impact the supply chain. There have been intermittent interruptions over the last several months, and our team, in partnership with Cardinal Health, works together to minimize any customer impact.

Pharmaceuticals Making Technetiumm Canadian scientists claim that cyclotron route to the medical-imaging isotope is the answer to shortages by William G. Schulz March 5, A version of this story appeared in Volume 90, Issue You might also like Most human exposure to technetium comes from the intentional use of Tcm in nuclear medicine.
Technetium can pose a health risk when it enters the body. Once in the human body, Tc concentrates in the thyroid gland and the gastrointestinal tract. However, the body constantly gets rid of Tc in feces.
As with any other radioactive material, there is an increased chance that cancer or other adverse health effects can result from exposure to radiation radiation Energy given off as either particles or rays. The Tcm used in medical diagnostics has a short, six-hour half-life and does not remain in the body. Skip to main content. Radiation Protection.
Today, Tcm is administered worldwide into more than 40 million patients annually. Considerable effort is being made by various countries, including the U. Certain options being considered include developing high-current electron accelerators that use x-ray technology to produce molybdenum, from which Tcm is made.
This research has immensely benefited humanity. Brookhaven National Laboratory is a multipurpose research institution funded by the U.
