Evaluation of solar ultraviolet radiation in Zanjan city using the ultraviolet index
Background and Objective: Monitoring the amount of ultraviolet radiation from sunlight can provide a basis for assessing people's exposure, raise public awareness and warn people against this radiation. Measuring the sun's ultraviolet index over a working period is an accurate choice to achieve this goal. Materials and Methods: In this study, the amount of solar UV index in one of the outdoor ...
متن کاملRefractive-index gratings written by near-ultraviolet radiation.
This is the first report, to our knowledge, of refractive-index grating side writing in 10 mol.% GeO(2)-doped fiber by the near-UV light of a cw Ar(+) laser (333-364 nm). An induced-index magnitude as large as 1.9 x 10(-4) at 1.7x10(5) W/cm(2) UV power density has been achieved. The observed gratings have exhibited the same temperature stability as gratings written by a KrF excimer laser (248 nm).
متن کاملSurface ultraviolet radiation over east Siberia: seasonal variations
The results of spectral measurements of the daily near-noon surface direct solar ultraviolet radiation in the wavelength range of 295–345 nm obtained in Irkutsk (East Siberia) for the time interval of 1998–2000 are presented. For the period under consideration, the seasonal UV radiation variations are analysed that are associated with the total ozone dynamics, the transition of cyclonic and ant...
متن کاملUltraviolet Radiation
another in the animal body. The full demonstration of the importance of transmethylation and of its relationship to the metabolism of choline, betaine, creatine, sarcosine, and a number of other methylated substances involved research that extended over a number of years. The discussion forms the subject matter of three of the chapters and requires considerably more than one-half of the book. I...
متن کاملThe measurement of solar ultraviolet radiation in Kermanshah city over a one-year period from 2015 to 2016
ABSTRACT Background: Ultraviolet radiation is present in sunlight. If ultraviolet radiation exceeds the limit, it can cause detrimental effects on human health such as skin cancer and cataract. Materials and Methods: In this descriptive cross-sectional study, the level of solar ultraviolet radiation type A (UVA) were measured using UV LOG HAND HELD in Kermanshah city. The intensity of ultravio...
