Plum Brook Reactor Facility FSSR, Attachment 13 Appendix B Rev. 0, Page 3 of 45 Appendix B Note:

1. Occasionally negative values of individual measurements appear in the tables in this appendix. In accordance with PBRF FSS/Characterization procedures, each measurement result in dpm/100-cm 2 is obtained by taking a shielded measurement and an unshielded measurement at each location established in the survey design. The shield is of sufficient thickness to completely attenuate (absorb) the most energetic beta from PBRF residual surface contamination (Sr/Y-90). The net activity is then determined as:

Net activity in dpm/I00-cm 2 = (Unshielded cpm - Shielded cpm): Where:

E, (A/100)

Unshielded cpm is the detector response including contributions from radiation entering the detector sensitive face (open area) and from ambient radiation (mostly gammas) entering the detector from all directions.

Shielded cpm is the detector response with the shield in place between the detector sensitive face and the surface being investigated. The shield eliminates beta particles from the surface under investigation and the detector response is due only to ambient radiation that enters the detector (from all directions).

(Unshielded cpm - Shielded cpm) is the net cpm due to activity, mostly beta particles entering the detector from the surface under investigation. Note that the net cpm includes contributions from residual contamination that may be present and from naturally occurring beta emitters in the material. This natural background component is considered to be small and is neglected, i. e., this background contribution is not subtracted in determining net cpm.

Detector efficiency, Et, dpm/cpm for the detector, is the product of the detector efficiency and the surface efficiency. A typical value of E, for the Ludlum 44-116 detector, the detector of choice for FSS systematic measurements in structures, is approximately 15% (0.15).

A/100 is the factor to convert dpm per detector area to dpm/1 00-cm 2, where A is the detector open area in cm 2. The open area of the Ludlum 44-116 is 100 cm2, so the (A/100) factor is unity in this case.

Negative values of net activity occur when the measured shielded cpm is greater than the measured unshielded cpm at a location. This most often occurs in survey units where residual contamination levels are low, near background, and the ambient background is also low. Thus, the random variability of low level count rates will result in occasional measurement pairs where the recorded shielded count rate exceeds the unshielded count rate.
