Groundwater is the principal pathway for the migration of most radiological and non-radiological compounds from past and present operating areas at Atomic Energy of Canada Limited’s Chalk River Laboratories (CRL). The CRL Groundwater Monitoring Program (GWMP) was established to measure the groundwater quality around the perimeters of areas affected, or potentially affected, by groundwater plumes. One of these is the NRX Rod Bays plume, a legacy plume that originated from the fuel storage bays of the National Research Experimental (NRX) reactor. This plume contains primarily 90Sr migrating along the groundwater flow system to the Ottawa River. A characterization study of the shoreline region was completed recently to map the plume discharge zone by collecting samples from mini-piezometers and groundwater seeps (springs) during a period of low river level. Analysis of discharging groundwaters determined that the 90Sr concentrations were very similar to those sampled from nearby (upgradient) GWMP monitoring wells. With this favorable correlation, the high density of seep and mini-piezometer sampling along the shoreline allowed refinements to be made in defining the northerly and southerly boundaries of the radiostrontium plume. The seep and mini-piezometer sampling also provided evidence that the monitoring wells sampled routinely within the CRL GWMP are positioned appropriately for providing representative sampling of the plume. Shoreline seep and mini-piezometer sampling can lead to refinements in the conceptual site model for plumes with limited effort and cost. The supplemental characterization work can also potentially identify other targets for routine groundwater monitoring.

“…Its main application is for the metrological purposes [7][8][9][10] but TDCR can be also used for routine quantitative determination of radionuclides [11,12]. However, in the available literature only few papers were published about using TDCR for quantitative measurements using Cherenkov counting [4,[13][14][15]. Therefore, the second goal of this paper is to show possibility of using TDCR Cherenkov counting for routine quantitative determination of high energetic beta emitters.…”

The Cherenkov counting efficiencies measured by three commercially available liquid scintillation counters, Triathler, Tri-Carb 3180, Hidex 300 SL were compared. The influences of energy of pure beta emitters, volume, and solvent as well as instrument type on Cherenkov counting efficiency were studied. The best Cherenkov counting efficiencies are on the Hidex 300 SL and when methanol is used as a solvent. It could be concluded that the sensitivities of low-level versions of Tri-Carb and Hidex 300 SL are comparable. Based on the overall results obtained it has been concluded that the TDCR Cherenkov counting is well suited for routine quantitative determination of low activities of high energetic beta emitters.
