Radiation Information Carbon Dating Radiocarbon dating has been one of the most significant discoveries in 20th century science. Renfrew said 'the radiocarbon revolution'.

The C14 technique has been and continues to be applied and used in many, many different jobs including hydrology, atmospheric science, oceanography, geology, palaeoclimatology, archaeology and biomedicine.

There are three principal isotopes of carbon which occur naturally - C12, C13 both stable and C14 unstable or radioactive. One carbon 14 atom exists in nature for every 1,, C12 atoms in living material. The radiocarbon method is based on the rate of decay of the radioactive or unstable carbon isotope 14 14Cwhich is formed in the upper atmosphere through the what is carbon dating gcse of cosmic ray neutrons upon nitrogen The nearly infinite energy that is stored in uranium atoms makes what is carbon dating gcse power possible. The interaction between three "heavy" elements - two types of uranium and a form of plutonium -- creates a chain reaction that can be harnessed to generate electricity.

The nuclear reaction generates heat that is used to boil water to create steam to drive a turbine to generate electricity.

Like fossil fuels, uranium is a finite non-renewable resource. Some of the most serious impacts linked to the generation of electricity on land can be linked to nuclear plants.

Where the amount of solid wastes generated at nuclear plants is small, these radioactive wastes pose health risks that are more than that of any other source of electricity. It is quite possible that these radioactive wastes will be stored for a century or more at existing nuclear plant sites, an idea that may stop any future re-uses of these contaminated lands.

Conclusion Nuclear medicine tests also known as scans, examinations, or procedures are safe and painless. In a nuclear medicine test, the radioactive material is introduced into the body by injection, swallowing, or inhalation.

Argon is a gas that does not ordinarily combine with other elements. So, when a mineral forms — whether from molten rock , or from substances dissolved in water — it will be initially argon-free, even if there is some argon in the liquid. However, if the mineral contains any potassium, then decay of the 40K isotope present will create fresh argon that will remain locked up in the mineral. Since the rate at which this conversion occurs is known, it is possible to determine the elapsed time since the mineral formed by measuring the ratio of 40K and 40Ar atoms contained in it. The argon found in Earth's atmosphere is
