do any one explain me pl. i would like to know the uncertainty error in measuring the specific activity of the primordial radionuclides
further on as Th-232 has to be estimated from the soil/sediments. as it is not a gamma ray emitter, the daughter product of Tl-208
do we need to multiply the amounts by 3. or the counts directly gives the acitivity of the Th-232.
whether poissons's distribution give the exact value of the errors associated at same instant of time.
