| Popis: | The presence of 226Ra, 228Ra and 210Pb in the production of oil is now a well-known phenomenon. An effort has been undertaken to establish quality control procedures and to produce an in-house reference material. Scale build-up has a significant amount of iron, barium and strontium and as such self-attenuation of photons, especially the 46.5 keV photon from 210Pb can significantly underestimate the radioactivity concentration. A procedure was developed to prepare an in-house standard using only a 20-g sample of scale obtained from west Texas. An evaluation of the homogeneity, counting procedures and determination of the self-attenuation factors are presented. |
