Radiometric dating Determination of age of carbon-containing artifacts up to about 70,000 years.

Also used as a biological tracer, for example, in studies of photosynthesis. Medical tracer used to locate brain tumours and problems with the lungs, thyroid, liver, spleen, kidney, gall bladder, skeleton, blood pool, bone marrow, salivary and lacrimal glands and heart blood pool and to detect infection. Positron emitters such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18 are produced in a cyclotron and are extremely short lived isotopes.

They have six protons in their nuclei and six electrons orbiting their nuclei, which gives carbon its chemical properties.

Orbiting around the nucleus are electrons (tiny particles each with a single electric charge).

The atoms in each chemical element may vary slightly in the numbers of neutrons within their nuclei.

Both are complete atoms in every sense of the word.

Rather, it is a transmutation process of changing one element into another.

Ages of many millions of years for rocks and fossils are glibly presented as fact in many textbooks, the popular media, and museums. One has only to wait: time itself performs the miracles.”1 Yet few people seem to know how these radiometric dating methods work.

For decades, the biologists have boldly proclaimed that, whereas we cannot observe today one type of creature evolving into a totally different type of creature, “Time is the hero of the plot. No one even bothers to ask what assumptions drive the conclusions.

An Italian team at the Politecnico di Torino, a well respected Italian University, claims the powerful magnitude 8.2 earthquake, which occurred in Old Jerusalem in the year 33 AD, would have been strong enough to release neutron particles from crushed rock.

According to scientists from Politecnico di Torino, radiation emissions caused by an earthquake may have confused carbon dating tests conducted in 1988 which suggested the cloth was only 728 years old, and therefore likely to be a forgery.

A longer half-life, such as hundreds or thousands of years, means that the radioisotope continues to emit harmful radiation for a very long period of time.

The table below gives the emitted radiation, half-life, and uses for a selection of useful isotopes in order of decreasing half-life.

So, for example, every carbon atom contains six protons and six electrons, but the number of neutrons in each nucleus can be six, seven, or even eight.
