Methods of Assessing Efficiency of UV-Protecting Products
International Journal of Occupational Safety and Ergonomics, 2002A few aspects of skin protection against ultraviolet (UV) light and methods of assessing efficacy of UV-protecting cream or gels have been discussed. UV-protection in cream and gels is not only a strategy of the cosmetic industry but a necessity because of human occupational activity and daily habits.

Dosimetry Methods for UV Radiation
Radiation Protection Dosimetry, 1997The main source of ultraviolet radiation is the sun, and individual habits with respect to sun exposure are important in assessing personal risk associated with ultraviolet radiation exposure. Ultraviolet radiation from other sources may contribute significantly to certain people's exposure.

Health Physics, 1997
In an attempt to reduce the incidence of skin cancer, cancer foundations have run educational campaigns which encourage the general population to limit their solar UVR exposures. An important part of these campaigns, in particular in Australia, but also more recently in Europe and the U.S., has been the adoption of protective measures such as ...

A method to estimate the UV content of illumination sources
SPIE Proceedings, 2011Where an illumination source includes flux in the UV region, an estimate of the total flux in the UV can be derived from the fluorescent efficacy of a reference material and the fluorescent emission from the material. A correlate of fluorescent efficiency was derived using a triangular weighting function in the fluorescent emission region and the flux ...

IEEE Antennas and Wireless Propagation Letters, 2004
Propagation over terrain and urban environments are studied using 2D simulations of Maxwell equations. For the case of terrain propagation, the multilevel UV method is used to accelerate the method of moments (MoM) solution. We consider propagation over a region of 14.42 km at 1,500 MHz that has 720,896 MoM surface unknowns.

UV laser methods and measurements
2015The ARGONTUBE UV laser system is a versatile instrument not only to infer information about the electric field, but also to measure the level of impurities present in the system. A good knowledge of the latter is required for the reconstruction of calorimetric information as the attenuation by electron attachment must be compensated for.

Standardization of Methods for Fluence (UV Dose) Determination in Bench-Scale UV Experiments
Journal of Environmental Engineering, 2003Ultraviolet (UV) disinfection is now an accepted technology for inactivation of a variety of waterborne pathogens in wastewater and drinking water. However, the techniques used in much of the previous research aimed at providing information on UV effectiveness have not yet been standardized.
