In 1947 a large collection of papyrus scrolls, including the oldest known manuscript version of the Old Testament, was found in a cave near the Dead Sea; they have come to be known as the “Dead Sea Scrolls”. The scroll containing the book of Isaiah was dated in 1994 using the radiocarbon technique and it was found to contain between 75% to 77% of the initial level of carbon 14. Radioactive decay is modeled by the function m (t) =...

An archeological artifact was subjected to radiocarbon dating. The artifact showed a carbon-14 decay rate of 12.2disintegrations/min per gram of carbon. Carbon-14 has a half-life of 5715 years, and currently living organisms decay at the rate of 15.3 disintegrations/min per gram of carbon. What is the approximate age of the artifact? Select one: A. 371 years old B. 6597 years old C. 851 years old D. 1867 years old

Question 4: Carbon dating (3 points) Archaeologists use the exponential, radioactive decay of carbon-14 to estimate the death dates of organic material. The stable form of carbon is carbon-12, and the radioactive isotope carbon-14 decays over time into nitrogen-14 and other particles. Carbon is naturally in all living organisms, and the carbon-14 that forms in the upper atmosphere enters into living things as long as they are taking in material (food, air, etc.) that contains carbon. We...

A certain radioactive substance decays at a rate proportional to its remaining mass M. a. Express this rate of decay as a differential equation. b. When a living organism dies it ceases to replace the carbon isotope C-14, and 48. the C-14 that is present decays with a half-ife of about 5730 years. If archeologists discover a fossilized bone that has 30% of the C-14 of a live bone, approximately how old is it?

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,...

(b) Write the two nuclear equations that are the basis for the radio-dating process that is based on carbon-14 (c) What types of materials can be radio-dated using carbon-14? (d) Briefly explain how the carbon-14 dating method works. (e) Radioisotope dating depends on constant rate of decay and formation of various nuclides in a sample. How is the proportion of carbon-14 kept relatively constant in organisms ? (f) How old does a sample have to be before the carbon dating...

A sample of charred animal bones found in a cave has a carbon-14 decay rate of 5.2 disintegrations per minute per gram of carbon (5.2 dis/min-g C). Living organisms have a decay rate of 15.3 dis/min-g C. The half-life of carbon-14 is 5715 yr. How old is the bone sample?
