Explain the concept of half-life in radioactive... - SS2 Physics Modern Physics - Nuclear Physics Question

The concept of half-life refers to the time it takes for half of the radioactive atoms in a sample to decay. It is a characteristic property of a radioactive isotope. The determination of half-life involves measuring the decay of a radioactive sample over a period of time. By plotting the decay curve and analysing the data, the half-life can be calculated. It signifies the rate at which radioactive decay occurs and provides a measure of the stability or instability of a radioactive material.
