Q2
The curie was originally intended to be the activity of one gram of radium-226. The actual weight of radium which is equal to one curie is (in gm)
T50 (Radius-226) = 1620 years
One curie = 3.7×1010 disintegrations (of atoms) per second (dps)
One year = 3.154×107 seconds

1 g of 14C from an archaeological sample gives 9.4 counts min1. 1 g of 14C from a recently cut tree given 15.3 counts min1 under the same conditions. How old is the archaeological sample? (T50 of 14C is 5730 years).

The lowest level 14C activity for experimental detection is 0.03 dis/min -g of 14C. The activity of 14C in atmosphere is 15 dis/min-g of 14C. The maximum age of an object that can be determined by 14C method is:
(t1/2of14C=5730year)
