The specific activity of radius is nearly-

STATEMENT-1 : Specific activity of the same radioactive substance is same for 10g radioactive substance as well as 50 g radiactive subsatnce. STATEMENT-2 : Specific activity of a radioactive subsance is its activity per g.

Which of the following exhibits specific activity in a catalytic reaction ?

A mixture of Pu""^(239) and Pu""^(240) has specific activity of 6xx10""^(9) dps. The half lves of isotopes are 2.44xx10""^(4) and 6.58xx10""^(3) years respectively. The percent of Pu""^(239) in the mixture is x/10% (nearly). Then 'x' is
