    The determination of UV intensity with a ferrioxalate actinometer is based on measurements of the electroreduction current of the Fe(III) oxalate complex during irradiation (chronoamperometry). The intensity emitted by KrCl and XeBr excilamps at wavelengths λ = 222 and 283 nm has been measured. For an intensity of 10-20 mW/cm2, the measurement error is ∼10%.
