How is radiation used in medicine?
Nuclear medicine procedures help detect and treat diseases by using a small amount of radioactive material, called a radiopharmaceutical. Some radiopharmaceuticals are used with imaging equipment to detect diseases. Radiopharmaceuticals can also be placed inside the body near a cancerous tumor to shrink or destroy it.
How do you get 99 Molybdenum?
Mo-99 is produced in the uranium-bearing targets by irradiating them with thermal neutrons. Some of the U-235 nuclei absorb these neutrons, which can cause them to fission. The fission of the U-235 nucleus produces two but sometimes three lower-mass nuclei referred to as fission fragments.
