Iodine-131 has a short half-life of 8 days, making it suitable for short-term studies without long-term radiation exposure. It emits gamma radiation, which can be easily detected by imaging techniques without causing significant tissue damage. It has similar chemical properties to stable iodine, allowing it to be incorporated into biological systems easily.

Phosphorous.
Technetium is an artificial element with applications as:Technetium-99m is largely used as tracer in radiodiagnostic.Technetium-99 is used as standard source for beta radiation.Technetium-95m is used as tracer in environmental studies.
Iodine-131 and cesium-137 are both radioactive isotopes, but they differ in their properties and uses. Iodine-131 has a relatively short half-life of about 8 days and is primarily used in medical applications, particularly in the treatment of thyroid conditions. In contrast, cesium-137 has a longer half-life of about 30 years and is commonly used in industrial applications, such as in radiation therapy and as a radioactive tracer. Additionally, iodine-131 emits beta and gamma radiation, while cesium-137 mainly emits gamma radiation.

In WWII it was phosphorus. They may have gone with something else nowadays.
Yes a tracer is a radioactive element whose pathway through the steps of a chemical reaction can be followed. It can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products.
