Abstract

Solar ultraviolet (UV) radiation measurement is an important aspect of dosimetry for the knowledge improvement of UV exposure with its associated health related issues. Small amounts of UV are essential for the production of vitamin D that is beneficial for human. Overexposure to solar UV radiation resulting in acute and chronic health effects on the human skin, eye and immune system. Many new instruments are developed in order to improve the measurement of solar UV radiation. In erythemal dosimetric measurement, few types of films developed to measure either direct or indirect solar UV radiation. Polysulfone film, polyphetylene oxide film and generation of EBT films are some of them. In order to analyze those films, spectrometer or scanner can be used to measure the films' optical absorbance. Pyranometer, pyrheliometer and UV meter are used as direct ground-based measurement tools in order to measure solar UV radiation. Satellite also one of the measurement techniques commonly employed to measure either UV irradiance or UV radiation on Earth's surface.
