The possibility of applying uranyl-oxalate actinometry at the intensities produced by highenergy flash discharges is investigated. It is shown that the photochemical decomposition of oxalate produced by a high-energy flash is directly proportional to intensity over an intensity range of 1000. Since the rate of decomposition at the lowest flash intensity is comparable with that calculated for the highest intensity previously studied in uranyloxalate actinometry, it is concluded that the quantum
