The ratio of C-14 to C-12 in a piece of wood from an archeological site was found to be only 0.354 of what it is in a piece of wood taken from a tree today. In years, what is the age of the wood based on this C-14 measurement? The half-life of C-14 is 5730 years. Provide answer rounded to the nearest year but do not put units in the answer box.

Therapy: Rodrigo was admitted to undergo Radioactive lodine therapy to complete his treatment of thyroid cancer. He was given 150 mCi of l-131 on Friday at 1:00pm. Due to a sudden heart attack, he died on Sunday, at 8:00am. Given a physical half-life of 8 days, and a biological half-life of 80 days, how much radioactive lodine is left in the corpse of Rodrigo at the time of his death?
The remnants of an ancient fire in a cave in africa showed a 146C decay rate of 3.9 counts per minute per grams of carbon. if the decay rate in C-14 in freshly cut wood, is 13.6 counts per mintue per gram of carbon, how many years ago did the campfire occur?
Fluorine-18, which has a half-life of 110 minmin, is used in PET scans. 2) If 120. mgmg of fluorine-18 is shipped at 7:00 A.M., how many milligrams of the radioisotope are still active when the sample arrives at the radiology laboratory at 4:10 P.M.?
Archeologists continue to debate the arrival of the first humans in the Western Hemisphere. Radiocarbon dating of charcoal from a cave in Chile was used to establish the earliest date of human habitation in South America as 8700 years ago. This procedure involves comparing the 14C present in a sample of charcoal to the 14C present in a living tree of the same age. What fraction of the 14C initially present remained in the charcoal after 8700 years? The half-life of 14C is 5730 years. (Write the answer as a number with a decimal.)
