The high x‐ray flux available at synchrotron radiation sources can cause nonlinearities in photon‐counting detectors unless deadtime corrections are employed. We compute the uncertainties associated with several common deadtime‐correction formulas. At lower countrates, statistical noise dominates the error in the measured countrates; at higher countrates, the dominating factors are saturation of the response and uncertainty in the value of the deadtime parameter. In between, a range of countrates exists in which the signal‐to‐noise ratio can be optimized for photon‐counting experiments.
