“…System validation is carried out using in-vivo comparative measurements (Quintern et al, 1997). The wavelength-specific calibration of VioSpor is carried out using measurements on the Okasaki spectrograph in Japan (lamp performance based on the US radiation strength norm of the National Institute of Standards) (Furusawa et al, 1998;Munakata et al, 2000).…”

Exposure to ultraviolet radiation (UVR) has long been recognized as the most important environmental risk factor for melanoma and skin cancer. Outdoor workers are among the groups most at risk from exposure to solar UVR in their daily activities. Sensitive spore-film filter-type personal dosimeters (VioSpor) were used to measure the biologically effective UVR received by construction workers in the course of their daily work. The study took place in Valencia, Spain, in July 2010 and involved a group of 8 workers for a period of 5 days. The median UV exposure was 6.11 SED/day, with 1 SED defined as effective 100 J/m 2 when weighted with the CIE erythemal response function. These workers were found to receive a median of 13.9% of total daily ambient ultraviolet erythemal radiation (UVER). Comparison with the occupational UVR exposure limit showed that the subjects had received UVER exposure in excess of occupational guidelines, indicating that protective measures against this risk are highly advisable.3

Ultraviolet (UV) radiation is part of the electromagnetic spectrum. The biological effects of UV radiation vary enormously with wavelength and for this reason the UV spectrum is further subdivided into three regions: UVA, UVB, and UVC. Quantities of UV radiation are expressed using radiometric terminology. A particularly important term in clinical photobiology is the standard erythema dose (SED), which is a measure of the erythemal effectiveness of a UV exposure. UV radiation is produced either by heating a body to an incandescent temperature, as is the case with solar UV, or by passing an electric current through a gas, usually vaporized mercury. The latter process is the mechanism whereby UV radiation is produced artificially. Both the quality (spectrum) and quantity (intensity) of terrestrial UV radiation vary with factors including the elevation of the sun above the horizon and absorption and scattering by molecules in the atmosphere, notably ozone, and by clouds. For many experimental studies in photobiology it is simply not practicable to use natural sunlight and so artificial sources of UV radiation designed to simulate the UV component of sunlight are employed; these are based on either optically filtered xenon arc lamps or fluorescent lamps. The complete way to characterize an UV source is by spectroradiometry, although for most practical purposes a detector optically filtered to respond to a limited portion of the UV spectrum normally suffices.

Background: Ultraviolet radiation (UVR) is known to be the most important risk factor for melanoma and non-melanoma skin cancers. Until today it has been impossible to measure reliably UVR in the frame of epidemiological studies. The recent development of a spore film containing spores of Bacillus subtilis resulted in a new method of UV measurement by personal dosimetry. Methods: The practical application of dosimeters was tested in 18 study persons under different circumstances of UV exposure and in 4 different geographical regions. Results: Eleven children carried dosimeters on their shoulders for 1 day, playing in- and outdoors on a sunny day in summertime. Their whole-day values ranged from 0.1 to 1.5 minimal erythema doses (MED) per day with a mean of 0.71 MED (±0.44). Four lifeguards in a public swimming-pool carried dosimeters on their shoulders for 11 days and received UV exposures ranging from 3.6 to 9.5 MED (mean 5.9 ± 1.88). Three mountain guides with dosimeters attached to the lateral head in different mountain regions at 23 mountaineering activities received daily exposures of 4.44–17.07 MED (mean 11.9 ± 3.8). Conclusion: B. subtilis spore film dosimeters can be applied to different study persons including children and mountain guides under different climatic conditions. A broad range of UV exposures can reliably be measured with this method.
