Assessment of the dose response of polysulphone film badges for the measurement of UV-radiation.

The dose response and accuracy of polysulphone film badges for monitoring UVB radiation (280-315 nm) were assessed by spectroradiometric measurements of the radiation source. A new formula is presented to calculate the UVB exposure of film badges. It is based on absorbance change at 330 nm and takes into account the saturation of the optical density of the badges. A good correlation was found between measured and radiated dose. Differences from previous formulae and limitations of the polysulphone films are discussed.
