Experimental Comparison of Empirical Material Decomposition Methods for Spectral CT [PDF]
, 2015 Material composition can be estimated from spectral information acquired using photon counting x-ray detectors with pulse height analysis. Non-ideal effects in photon counting x-ray detectors such as charge-sharing, k-escape, and pulse-pileup distort the

Terrestrial Consequences of Spectral and Temporal Variability in Ionizing Photon Events [PDF]
, 2006 Gamma-Ray Bursts (GRBs) directed at Earth from within a few kpc may have damaged the biosphere, primarily though changes in atmospheric chemistry which admit greatly increased Solar UV. However, GRBs are highly variable in spectrum and duration.
