Methods of evaluating a superabrasive volume or a superabrasive compact are disclosed. One method may comprise exposing a superabrasive volume to beta particles and detecting a quantity of scattered beta particles. Further, a boundary may be perceived between a first region and a second region of the superabrasive volume in response to detecting the quantity of scattered beta particles. In another embodiment, a boundary between a catalyst-containing region and a catalyst-diminished region of a polycrystalline diamond volume may be perceived. In a further embodiment, a boundary may be perceived between a catalyst-containing region and a catalyst-diminished region of a polycrystalline diamond compact. Additionally, a depth to which a catalyst-diminished region extends within a polycrystalline diamond volume of a polycrystalline diamond compact may be measured in response to detecting a quantity of scattered beta particles. A system configured to evaluate a superabrasive volume is disclosed.
