WebRadioisotopes give off energy that can be detected by special equipment. When small quantities are introduced into the body, the imaging equipment tracks their location and movement. This enables the doctors to learn more about the diseased tissues than a diagnostic procedure that just takes a picture from the outside. WebMar 6, 2024 · Isotopes are named after the "mass number," or the sum of protons and neutrons in one atom. [4] This means Ag-109 has two more neutrons per atom than Ag-107, giving it slightly more mass. 2 Look up the mass of each isotope. inability to recognize familiar facesWebDec 2, 2024 · Commercially, the U 235 isotope is enriched to 3 to 5% (from the natural state of 0.7%) and is then further processed to create nuclear fuel.

WebSep 29, 2016 · A neutron is shot at the nucleus and is absorbed, causing instability and fission. In some elements—such as certain isotopes of uranium and plutonium—the fission process also releases excess neutrons, which can trigger a chain reaction if they’re absorbed by nearby atoms. WebSep 29, 2016 · Modern nuclear weapons work by combining chemical explosives, nuclear fission, and nuclear fusion. The explosives compress nuclear material, causing fission; …

WebIf each isotope was in equal proportions (eg. each made up 50%) that would work, but that isn't the case here. One isotope makes up ~99% of all carbon, the other makes up ~1%. Clearly the isotope that makes up 99% needs to be given more importance. There is more than one way to take an average. WebFeb 16, 2024 · Radioisotope power systems (RPS) convert heat generated by the natural decay of plutonium-238 —a radioactive isotope—into electrical power. They have powered more than two dozen U.S. space missions and are capable of producing heat and electricity under the harsh conditions in deep space for decades without any maintenance.
