a The azimuthally integrated intensity, I(q, t), as a function of momentum transfer, q. The color indicates the absorbed dose \({{{{{{{\mathcal{D}}}}}}}}\) and the corresponding timescales. The data shown are acquired with a dose rate of 2.04 kGy μs−1. The inset displays I(q, t) normalized to the first pulse I(q, 0). b Porod invariant, \({Q}_{P}({{{{{{{\mathcal{D}}}}}}}})\), calculated from the data displayed in a (orange) and three additional dose rates. The data are normalized to QP(0) and the error bars are calculated as the standard deviation of the normalized second pulse from unity. The inset shows the mean of \({Q}_{P}({{{{{{{\mathcal{D}}}}}}}})\) below 10 kGy for different dose rates. The error bars indicate the weighted standard deviation of QP in this range. Source data are provided as a Source Data file.
