What does technetium-99m detect?

Tc-99m is the preferred tracer for a number of scans used in medicine worldwide to help diagnose medical conditions. Tc-99m scans are used to detect a wide range of conditions including injuries, infections, tumours, heart disease, thyroid abnormalities, kidney conditions and also to guide some cancer procedures.

Which of the following is a measure used to describe the amount of radioactivity in a sample of material?

What is the Curie actually measuring?

One of three units used to measure the intensity of radioactivity in a sample of material. A curie is also a quantity of any radionuclide that decays at a rate of 37 billion disintegrations per second (1 gram of radium, for example).

How is technetium 99m eliminated from the body?

Technetium and Health However, the body constantly gets rid of Tc-99 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..
