The beta radiation of the isotope carbon-14 is measured.
Carbon-14.
Half of a radioactive isotope refers to the time it takes for half of the original amount of the isotope to decay. This is known as the isotope's half-life. It is a measure of the stability of the isotope, with shorter half-lives indicating more rapid decay.
The mass number for a particular isotope of an element is a precise value. The average atomic mass for an element is the value you would measure for that element given all the isotopes it has and their abundance in the sample.
The radioactive isotope is disintegrated in time and emit radiations.
The isotope 22Na is radioactive but the concentration is extremely low. A measure of the radioactivity is not necessary.
The beta radiation of the isotope carbon-14 is measured.
Carbon-14.
simply, it measure the activity of a radioactive isotope in Ci "curie" or in Bq "Becquerel"
Carbon 14 is the isotope of carbon measured in radiocarbon dating.
A mass spectrometer is the instrument used to measure the relative abundance of an isotope. It does this by separating isotopes based on their mass-to-charge ratio and providing a qualitative and quantitative analysis of the isotopic composition of a sample.
The most common is carbon 14.
The basic idea is to measure the amount of the radioactive isotope, and of one or more of its decay products. The older the rock, the larger the percentage of the original isotope that decayed - so the ratio between the original isotope and the decay product changes over time.

The stable isotope formed by the breakdown of a radioactive isotope is called a daughter isotope. This process is known as radioactive decay, where a radioactive isotope transforms into a stable daughter isotope through the emission of particles or energy.
