Radioactive tracers are used in science to track the movement of molecules in biological systems. By incorporating a radioactive isotope into a molecule, scientists can follow its distribution and transformations within living organisms or chemical reactions. This technique is valuable for studying metabolic pathways, identifying diseases, and investigating physiological processes.

Radioactive tracers are short-lived?
That is correct. Radioactive tracers have a short half-life, which means they decay quickly and are no longer detectable after a short period of time. This property makes them useful for tracking processes in a relatively short time frame without long-lasting radiation exposure.
Which technique is also known as a scintigram?
A scintigram refers to a diagnostic imaging technique called scintigraphy, which uses radioactive tracers to produce images of organs and tissues in the body. It is commonly used in nuclear medicine to evaluate various medical conditions.
What is radioactive half-life used for?
Radioactive half-life is used to measure the rate at which a radioactive substance decays. It is important in determining the amount of time it takes for half of a radioactive substance to decay into a stable form. This information is useful in various fields such as medicine, environmental science, and geology for dating purposes and evaluating risks associated with radioactive materials.
Positron-emission tomography forms images of body tissues this is known as what?
Positron-emission tomography (PET) forms images of body tissues using radioactive tracers that emit positrons. This imaging technique is used to detect functional processes in the body, such as metabolism or blood flow, and is commonly used in medical diagnosis and research.
How is Einstein's equation Emc2 used in medicine?
In medicine, Einstein's equation E=mc^2 is used in nuclear medicine for procedures such as PET scans. This equation demonstrates the concept of mass-energy equivalence, where a small amount of mass can be converted into a large amount of energy. In PET scans, positron-emitting radioactive tracers are used to detect anomalies in the body, and the energy released from their annihilation with electrons is detected to create images.
Give two examples of how tracers are used .tell why radioactive isotopes work as tracers?
Alloys
What isotopes are used as radioactive tracers?
Either beta or gamma
What are new radioactive tracers and PET scans used for?

Give two examples of how tracers are used tell why radioactive isotopes work as tracers?
Tracers like technetium-99m are used in medical imaging to diagnose conditions like cancer and heart disease. In environmental science, isotopes like carbon-14 are used to trace the movement of pollutants in ecosystems. Radioactive isotopes work as tracers because they can be easily detected using specialized equipment, allowing scientists to track their movement and behavior with high sensitivity and accuracy.
What is the source of radioactive tracers in pipes?
Radioactive tracers in pipes can come from various sources such as leakages from nuclear facilities, medical facilities that use radioactive materials for treatments, or industrial processes that involve radioactive isotopes. These tracers are used to detect leaks, blockages, or flow patterns in pipes.
How are radioactive isotopes useful to researchers?
Radioactive isotopes are used is:- medicine, for treatment by irradiation- medicine, for diagnostic- in science/technology as tracers- as source of energy- as source of ionizing radiations- in many instruments- determination of rocks ageetc.
Are radioactive isotopes are used in medicines or power plants and tracers true of false?

How is a radioactive isotope helpful in medicine?
In medicine isotopes are used for treatments, diagnostics or as tracers.
What are two uses for radioactive tracers?
Radioactive tracers are used in medicine for imaging procedures like PET scans to detect abnormal tissues or diseases. They are also used in environmental studies to trace the movement of substances in ecosystems or to monitor water flow in rivers and oceans.
