A piece of wood from an aechaeological source shows a C - 14 activity which is 60% of the activity found today. Calculate the age of the sample `t_(1//2)`for`""_(6)^(14)C` = 5770years).

A

3515 years

B

300 year

C

4253 year

D

4000 years

Text Solution

Verified by Experts

The correct Answer is:
C
`lambda = (0.693)/(5770) yr^(-1), t = (2.303)/(0.693//5770) "log" (100)/(60)`
`= 4253` years.

A wooden artifact sample gave activity 32-beta particles per second while the freshly cut wood gave activity of 64 beta particles per second in Geiger Muller counter. Calculate the age of the wooden artifact (t_(1//2) "of" C^(14) = 5760 years)

The beta- activity of a sample of CO_(2) prepared forma contemporarty wood gave a count rate of 25.5 counts per minute (cp m) . The same of CO_(2) form an ancient wooden stratue gave a count rate of 20.5 cp m , in the same counter condition. Calculate its age to the nearest 50 year taking t_(1//2) for .^(14)C as 5770 year. What would be the expected count rate of an identical mass of CO_(2) form a sample which is 4000 year old?
