How are isotopes used in the human body?

Stable isotopes have been used as tracers in human nutritional studies for many years. A number of isotopes have been used frequently to assess body composition, energy expenditure, protein turnover and metabolic studies in general, such as deuterium (2Hydrogen), 18Oxygen, 13Carbon and 15Nitrogen.

How radioactive isotopes are used in the body?

Nuclear medicine uses radioactive isotopes in a variety of ways. One of the more common uses is as a tracer in which a radioisotope, such as technetium-99m, is taken orally or is injected or is inhaled into the body. The radioisotope then circulates through the body or is taken up only by certain tissues.

How are isotopes used in medical diagnosis?

A radioisotope used for diagnosis must emit gamma rays of sufficient energy to escape from the body and it must have a half-life short enough for it to decay away soon after imaging is completed. The radioisotope most widely used in medicine is Tc-99, employed in some 80% of all nuclear medicine procedures.

What is the isotope used in brain scans?

The procedure involves the injection of a radioactive isotope (such as technetium-99m or iodine-131) into a blood vessel that supplies the cranial region.

Why are isotopes so important?

Isotopes of an element all have the same chemical behavior, but the unstable isotopes undergo spontaneous decay during which they emit radiation and achieve a stable state. This property of radioisotopes is useful in food preservation, archaeological dating of artifacts and medical diagnosis and treatment.

What are the dangers of isotopes?

Breathing in radioisotopes can damage DNA. Radioactive isotopes can sit in the stomach and irradiate for a long time. High doses can cause sterility or mutations. Radiation can burn skin or cause cancer.

What is the function of isotopes?

They are typically useful when performing experiments in the environment and in the field of geochemistry. These isotopes can help determine the chemical composition and age of minerals and other geologic objects. Some examples of stable isotopes are isotopes of carbon, potassium, calcium and vanadium.

Who is the creator of body and Brain Connection?

Developed under the supervision of renowned Japanese neuroscientist Dr. Ryuta Kawashima, Body and Brain Connection revolutionizes the mega-popular Brain Training genre he helped originate with an all-new, unique blend of physical and cerebral challenges.

What can you do with body and Brain Connection?

Body and Brain Connection will test the whole family to think quickly and act even quicker as they compete in 20 unique activities ranging from math, logic, reflex, memory and physical-related exercises using the full-motion capabilities of the Kinect sensor.

Is there a game called body and Brain Connection?

From the originators of the video game brain training craze, Body and Brain Connection challenges players to think on their feet in one of the most cerebral and energetic party games.

How many people can play body and Brain Connection?

Body and Brain Connection also supports up to four players in a fun and energetic multiplayer mode. Compete against friends and family to determine who has the youngest brain age, or who has the best score across any of the game’s 20 exercises.
