Primary standard detectors based on an ionizing chamber and a pneumatic Golay detector have been developed at VNIIOFI to cover the spectral range 30 nm to 400 nm. The double ionizing chamber was used over the spectral range 30 nm to 126 nm and the Golay detector to cover the range from 105 nm to 400 nm. The main advantage of the Golay detector is its high level, non-selective responsivity of 103 V W−1. The responsivity threshold is 10−10 W Hz−1/2. Pulsed synchrotron radiation sources were used for UV beam generation. These small synchrotrons have strong magnetic fields and emit a high intensity, controllable spectrum. A transfer standard multichannel radiometer was used for the measurement of UV-A, UV-B and UV-C irradiance, which permitted the determination of the bactericide, erythemous and generally harmful UV action spectra. The development of primary and transfer standard detectors allowed the establishment of basic national standards for UV radiometry.
