NORM contamination in pits and ponds pose a particular challenge in terms of manpower and cost using current sampling and evaluation methods. Physical conditions and sample costs often limit the number of samples that are collected, and potentially results in serious errors in estimating NORM waste.This paper will discuss a direct in-situ measurement technique to detect radium-226 which has been developed to overcome the limitations of standard NORM sampling techniques. Operational experience has demonstrated the effectiveness of this method for remediation which provides low cost and near real-time analysis for radium-226 in the subsurface. A case study is presented using this technique for a NORM pit remediation.IntroductionThe development of in-situ radium-226 analysis originated with the need to rapidly characterize and monitor subsurface conditions for assessment and remediation of NORM contaminated pits and ponds with data resolution on the order of 15 cm. The technique is an outgrowth of methods that are applied routinely in both the uranium mining and petroleum industries for subsurface measurement of natural and man-made radioactive isotopes. The in-situ analysis technique presented here relies on gamma-ray spectrum analysis to measure radium-226 daughter isotopes at NORM contaminated sites without the need to collect physical samples at each sample interval. This in-situ technique has been effectively applied to the characterization and remedial monitoring of a submerged NORM contaminated waste pit where physical collection of samples from all NORM contaminated zones of interest would have been economically and technically prohibitive.P. 253 Keywords: society of petroleum engineers, norm contamination, spe 029714, analysis method, instrument reading, reduction, calibration, depth interval, instrument, contamination Subjects: Environment, Information Management and Systems, Naturally occurring radioactive materials This content is only available via PDF. 1995.
