From: Gamma detector dead time correction using Lambert W function
Dead time corrections for the OW measurement of the phantom. Sensitivity (COW) in kcps/MBq vs. A (MBq) for the second extrinsic phantom measurement, detector 1, open window, with values of τOW from different measurements used for correction: blue diamonds, uncorrected; red squares, τOW from the intrinsic point source measurements (from Table 2); green triangles, τOW from the first extrinsic point source measurement (Table 4); and cyan circles, τ value of Silosky [3] (based on MCR).
