The charred bones of a sloth in a cave in Chile represent the earliest evidence of human presence at the southern tip of South America. A sample of the bone has a specific activity of 5.22 disintegrations per minute per gram of carbon (d/min*g). If the 12Cy14C ratio for living organisms results in a specific activity of 15.3 d/min*g, how old are the bones (t1/2 of 14C = 5730 yr)?
A sample of radioactive material is obtained from a very old rock. The activity of the rock over a period of time is monitored, and lnA is plotted as a function of t such as in Figure (b). The slope of the line has a value of -6.1 ×10^−8y^−1.
FInd the half-life in years.
In 1991, two hikers in the Alps, between Italy and Austria,
discovered the remains of a well-preserved mummy that dates back to the Ice Age.
The activity of C-14 in the remains of the Iceman was measured to be 0.1220 Bq per gram.
In a living organism the rate of radioactive decay of C-14 is 0.2310 Bq per gram.
Determine how long ago the Iceman lived.
The half-life of C-14 is 5730 years.
