As a result, medical procedures using radiation have saved thousands of lives through the detection and treatment of conditions ranging from hyperthyroidism to bone cancer.

These instruments provide doctors with color images that show the shapes and details of internal organs.Excess Xenon-135 is a radioactive isotope of xenon, produced as a fission product of uranium.It has a half-life of about 9.2 hours and is the most powerful known neutron-absorbing nuclear poison (having a neutron absorption cross-section of 2 million barns).When used in this way, they are most often intended to kill cancerous tissue, reduce the size of a tumor, or reduce pain.

For example, radioactive iodine (specifically iodine-131) is frequently used to treat thyroid cancer, a disease that strikes about 11,000 Americans every year.Today, to benefit humankind, radiation is used in medicine, academics, and industry, as well as for generating electricity.In addition, radiation has useful applications in such areas as agriculture, archaeology (carbon dating), space exploration, law enforcement, geology (including mining), and many others.The shadow of the pencil is revealed because most light has enough energy to pass through the paper, but the denser pencil stops all the light.
