Why can’t carbon -14 dating be used for ages 50,000 year and older?
Homework Answers
Radiocarbon dating is generally limited to dating samples no more than 50,000 years old, as samples older than that have insufficient 14C to be measurable. Older dates have been obtained by using special sample preparation techniques, large samples, and very long measurement times. These techniques can allow dates up to 60,000 and in some cases up to 75,000 years before the present to be measured

Carbon dating is relatively accurate back to 50000 years. Older samples require either special preparations of C-14 or a different atomic isotope needs to be used. Explain why carbon dating is only accurate with samples that are 50000 years old or younger.

Question 23 of 23 Carbon-14 is a radioisotope that is used for dating biological organisms. The half-life of C-14 is 5730 years. When a 1 g sample of carbon from fresh peat is measured for radioactivity, 900 beta decays are recorded every hour A 1 g sample of carbon is obtained from a peat deposit and is measured for radioactivity. If 113 beta decays are observed every hour, how many half-lives of C-14 have passed since the deposit was formed?...

In the carbon dating process for measuring the age of objects, carbon-14, a radioactive isotope, decays into carbon-12 with a half-life of 5730 years. A Cro-Magnon cave painting was found in a cave in Europe. If the level of carbon-14 radioactivity in charcoal in the cave is approximately 16% of the level of living wood, estimate how long ago the cave paintings were made. (Hint: Let the initial amount of carbon-14 be C0. Round your answer to the nearest year.)

Carbon-14 is a radioisotope that is used for dating biological organisms. The half-life of C-14 is 5730 years. When a one-gram sample of carbon from fresh peat is measured for radioactivity, 900 beta decays are recorded every hour. A one-gram sample of carbon is obtained from a peat deposit and is measured for radioactivity. If 113 beta decays are observed every hour, how many half-lives of C-14 have passed since the deposit was formed? A. 1/8 B.3 C.113 D.8 Approximately...

1. The half-life of carbon-14 is 5730 years. A sample is found to have one-eighth the original amount of carbon-14 in it. How old is the sample? 5730 years, 716 years, 45800 years, 17200 years 2. Why wouldn't you use carbon-14 dating on a piece of shell that was estimated to be 1 million years old? Sea shells do not have radioisotopes, carbon dating is only useful on plants, uranium dating is better for items older than 1/2 million years,...

Radiometric dating is often used to calculate the ages of rocks. Explain the principles of radiometric dating using the words “parent”, “daughter products” and “half-life”. Also Uranium-235 has a half-life of 700 million years. What fraction of the original amount of parent material will remain after 2.1 billion years?
