What is 111in?

111In (indium-111) is a radioactive isotope of the element indium with 49 neutrons and 49 protons. It emits gamma radiation and has a half-life of approximately 2.8 days.

It is commonly used in medical imaging, particularly in nuclear medicine, for imaging various organs and tissues in the body. It is often used in combination with a radiopharmaceutical that specifically binds to certain tissues or cells, allowing for targeted imaging.

Additionally, 111In can be used for targeted radiation therapy of certain types of cancer. It has also been used in research applications, such as in studies of gene expression in cells.

However, as with all radioactive materials, proper handling and disposal procedures must be followed to minimize radiation exposure and environmental contamination.
