Dear all,

I am looking for more information how specific activity $\frac{Bq}{g}$ and surface activity $\frac{Bq}{cm^2}$ is measured. This is done to determine whether the materials of interest can be treated as harmless and disposed as usual waste. I am interested how the experimental procedure looks like. I don't know how the name is in English, but in German this is called "Freimessung" Actually one measures the activity $A_i$ and compares it to given limits $FG_i$ using sums of the form
$$\sum_i \frac {A_i}{FG_i} < 1$$
