The greater the initial concentration of the parent, the greater the concentration of the radiogenic daughter isotope will be at some particular time.
12.
The CAESAR reactor design exploits the fact that the fission products and daughter isotopes produced via nuclear reactions also decay to produce additional delayed neutrons.
13.
The above equation makes use of information on the composition of parent and daughter isotopes at the time the material being tested cooled below its closure temperature.
14.
:: : : : : The actual rods are a very complex mixture of the uranium dioxide fuel, compounds containing daughter isotopes and other materials.
15.
Monazite geochronology studies the ratio of parent isotopes to daughter isotopes ( isotopic ratio ), and calculates how much time has passed since daughter isotopes start accumulating.
16.
Monazite geochronology studies the ratio of parent isotopes to daughter isotopes ( isotopic ratio ), and calculates how much time has passed since daughter isotopes start accumulating.
17.
They usually dispute these methods based on uncertainties concerning initial concentrations of individually considered species and the associated measurement uncertainties caused by diffusion of the parent and daughter isotopes.
18.
However, construction of an isochron does not require information on the original compositions, using merely the present ratios of the parent and daughter isotopes to a standard isotope.
19.
The radioactive decay of elements in the Earth's mantle and crust results in production of daughter isotopes and release of particles and heat energy, or radiogenic heat.
20.
However, as the mineral cools and the crystal structure becomes more complete, the diffusions of parent and daughter isotopes slows down and finally become insignificant at a certain temperature.
