Have teams use their charts to find their isotope's half-life. A half-life is a measure of the average lifetime of a radioactive substance, and specifies the time it takes for one-half of the ...

Stable isotopes do not decay into other elements. In contrast, radioactive isotopes (e.g., 14C) are unstable and will decay into other elements. The less abundant stable isotope(s) of an element have ...

These isotopes are essential for making targets ... discovered alpha and beta rays and proposed the laws of radioactive decay. The name rutherfordium was decided upon after a long debate between ...

An isotope emits gamma rays that easily pass through the body to a detector outside the body, for example a ‘gamma camera’. In this way, the radioactive isotope can be followed as it flows ...
