Question: "Is carbon dating a reliable method for determining the age of things? Several factors affect radiocarbon test results, not all of which are easy to control objectively. Carbon dating is reliable within certain parameters but certainly not infallible. When testing an object using radiocarbon dating, several factors have to be considered: First, carbon dating only works on matter that was once alive, and it only determines the approximate date of death for that sample. For example, a steel spearhead cannot be carbon dated, so archaeologists might perform testing on the wooden shaft it was attached to.

Alpha is 2 protons and 2 neutrons is the most ionising but the least penetrating. It is the most dangerous but is stopped by a few cm of air or a piece of paper. Beta is a high speed electron from the nucleus. It is moderately ionising and stopped by a few cm of aluminium. Gamma is a high frequency electromagnetic wave and is the least ionising but the most penetrating. It is the least dangerous but is only stopped by a few.
Radiocarbon helps date ancient objects—but it's not perfect
Chapter 9: Geologic Time Concept 5 Quiz. Why is radiometric dating the most reliable method of dating the geologic past? Radiometric dating allows us to determine the order of events, therefore we have constructed the geologic time scale from those data.
This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature. C is by far the most common isotope, while only about one in a trillion carbon atoms is C C is produced in the upper atmosphere when nitrogen N is altered through the effects of cosmic radiation bombardment a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope. The new isotope is called "radiocarbon" because it is radioactive, though it is not dangerous. It is naturally unstable and so it will spontaneously decay back into N after a period of time.
