Performed using solid state silicon detectors. Two types of analyses are available:

Option 1: All isotopes are counted using a single source.

Option 2: Alpha emitters are isolated and chemical interferences are removed using extensive radiochemistry. Actinide separation techniques are employed to produce sources free of spectral overlap and tracer additions are used to determine yields.

Detection limits listed below refer to option 2. In general, detection limits for option 1 will be an order of magnitude higher.
