Abstract
For determining whether oil waste at a field testing site is exempt from selected naturally occurring radioactive material (NORM) waste regulations, a measurement apparatus including a detection module that determine radioactivity counts per minute for an oil waste sample is utilized. The measurement apparatus includes an analysis module that uses a first nonlinear transfer function to determine a mass for the oil waste based on a volume of solids determined via BS&W testing. The analysis module uses a second nonlinear transfer function to determine a maximum radioactivity level for the sample which is then normalized to picoCuries/g. The normalized maximum radioactivity level per gram is compared to a NORM exemption level for a selected region and communicated to entities at the field-testing site and optionally to other entities. A system and a method perform the functions of the measurement apparatus.
