This work demonstrated the combined utility of empty tube subtraction, over-modulation, native signal subtraction and spectral filtration in low level dosimetry using commercial sugar samples. The native signal component was found to have an effective peak to peak equivalent of 150 mGy. If the zero dose native signal is accurately modeled and subtracted, the detection limit was estimated to be 0.2 Gy although intercept uncertainties were as low as 25 mGy. This was enabled by resultant slope uncertainties as low as 3% with residual variations of approximately 0.1 Gy.
