carbon-14 dating
i need the answer not this
carbon-14 dating
Carbon dating
BLANK BLANK AND STUPID OLD BLANK Answer: There are two possible answers to your question. 1. Carbon dating. 2. Forensic Entomolgy. The use of insects in death investigations.
Scavengers can estimate when an animal is in distress and they will gather and wait. They will strike when they are ready, even if the animal is still alive but very weak.
For things that were once living the best method is what is called Carbon Dating, which is based on the decay of carbon-14. As long as the thing remains alive it is in equilibrium with the environment and maintains a constant level of carbon-14 in its tissues. On death this equilibrium is broken and the remaining carbon-14 slowly decays away without anymore replacing it from the environment. The age can be calculated by measuring how much carbon-14 has been lost from the equilibrium level.The problems with Carbon Dating is that it does not work for things that died more than 40,000 years ago due to the fact that the halflife of carbon-14 is 5570 years so after 40,000 years there isn't enough left to measure, and the environmental level of carbon-14 does change some over time so known reference sources (e.g. tree rings) must be used for recalibration of Carbon Dating results.Beyond 40,000 years other radiometric dating methods must be used, but unlike Carbon Dating they cannot determine age from death.
Carbon dating cannot be used on living organisms since the method measures the decay of carbon-14 isotopes over time. In living organisms, the carbon-14 levels remain constant due to continuous intake through the food chain. Once the organism dies, the carbon-14 levels begin to decline, allowing for dating of the organic material.

One valuable method is radiocarbon dating. All living things absorb a small amount of radioactive carbon(C-14) from the atmosphere. After a living thing dies it slowly loses C-14. a scientist can calculate the age of an object by measuring the amount of C-14 left in it. Another method is thermoluminescence dating. This dates and object by measuring the light given off by electrons trapped in the soil surrounding fossils and artifacts.
