Radioactive disintergation always follow I order kinetics and is independent of all external factors and is represented by the relation N = N_(0) e^(-lambda t) where lambda is decay constant and N atoms are left at time t . The radioactive nature of element is expressed in terms of average life numerically equal to decay constant (1//lambda) however all the radioactive do not lose their radioactive nature in thier average life. The radioactive emission involves alpha, beta particles as well as gamma- rays.The penertrating power order is alpha lt beta lt gamma . The emissions can perntrate even thick steel walls but are however unable to penttrate Pb blocks. The S unit fo rate of decay is dps .

The fossil bone has a .^(14)C : .^(12)C ratio, which is [(1)/(16)] of that in a living animal bone. If the half -life of .^(14)C is 5730 years, then the age of the fossil bone is :
