Fig. 4From: Gamma detector dead time correction using Lambert W functionLambert dead time corrected count rates vs. activity. Measured and corrected count rates (kcps) vs. A (MBq), based on Eq. (3), using τ values from Table 2, for the intrinsic measurement for detector 1 for both energy windows: OW and 99mTc. The slope of the corrected curve equals sensitivity, CBack to article page
