Evidence of an underlying trend in the dependence of erythema effective ultraviolet (UV) radiant exposure (Her) on changes in the total ozone, cloud cover and aerosol optical depth (AOD) has been studied using solar ultraviolet radiation measurements

The United Kingdom sporadically experiences low ozone events in the spring which can increase UV to harmful levels and is particularly dangerous as sunburn is not expected by the public at this time of year. This study investigates the benefits to th

There is a drive to energy efficiency to mitigate climate change. To meet this challenge, the UK Government has proposed phasing out incandescent lamps by the end of 2011 and replacing them with energy efficient fluorescent lighting, including compac

Clothing can provide substantial protection against solar ultraviolet radiation (UVR) and quantifying the amount of protection can have useful applications to recreational, occupational and medical situations. However, exposure of fabrics to sunlight

Overexposure to solar ultraviolet radiation (UVR) in childhood is considered to be a critical factor for developing skin cancer in later life. Clothing may offer a simple and effective means of protection against overexposure to the sun, but its use

A number of industrial applications and public services involve occupational exposure to ultraviolet radiation (UVR) from a variety of lamps and lasers. The aim of this study was to develop a methodology for the assessment of the UV protection level

Lasers have been used for entertainment almost since their first practical operation reported in 1960. Laser displays started in 1973. There is no doubt that the uses of lasers for entertainment are impressive. However, there are a number of safety i

An analysis of the temporal variation in the erythemally weighted UVB/UVA irradiance ratio using spectral data collected from a monitoring site in Chilton, UK (51°N) for the 5-y period from 2004 to 2008 is presented. The variation in the diurnal rat
