Does anyone know of a basis for determining if the source of radioactivity on a smear or air sample is natural, fission product or transuranic based on the alpha to beta ratio.
For example, if the ratio is greater than 3 then the source could be Actinide; it the ratio is less than 0.5, the source could be fission product; if the ratio is between then natural radioactivity is indicated.
Does anyone know of a reference for these ratios?
