Ultraviolet radiation is known to cause both benefits and harmful effects on humans. The adverse mainly involve two target organs, skin eye, can be further divided into short- long-term effects. present case report describes an accidental exposure of health-care workers ultraviolet produced by a germicidal lamp in hospital pharmacy. presented spectrum with intense UV-C component as well modest UV-B contribution. Overexposure was over 100 times large the ICNIRP limits. A few hours after...

Within an epidemiological study regarding the correlation between skin pathologies and personal ultraviolet (UV) exposure due to solar radiation, 14 field campaigns using polysulphone (PS) dosemeters were carried out at three different Italian sites (urban, semi-rural rural) in every season of year. A calibration curve for each experiment was obtained by measuring ambient UV dose under almost clear sky conditions corresponding change PS film absorbance, prior post exposure. Ambient doses...
Plasma behaviour in the high density regime has been investigated on Frascati Tokamak Upgrade (FTU). The items particularly addressed are limit, MARFE characteristics and fuelling efficiency. With gas puffing, a maximum line average of 3.2*1020 m-3 obtained ohmic at q=5.1, corresponding to 1.7 times Greenwald limit; while with pellet injection, value 3.7*1020 reached q=3.5. limit appears be connected impurity content edge parameters, so best results very clean plasmas peaked electron...

Operating with a high frequency and wave guide antenna, the ion Bernstein (IBW) experiment on Frascati Tokamak Upgrade is not dominated, as expected, by nonlinear plasma edge phenomena. By coupling IBW power, simultaneous increase of density central electron temperature (⩾2 keV) produced when confinement magnetic field adjusted to set an cyclotron resonant layer in bulk.

Ultra violet (UV) solar energy can cause several negative effects to the skin and eyes in case of overexposure. To protect people from erythemal damage, personal exposure must be carefully assessed when outdoor activities are carried out. The direct measure with scientific instruments is impracticable common people, indirect methods assess only on horizontal plane: this work developed a mathematical model all body districts. UVA irradiance were measured inclined planes, oriented four...

Due to meteorological conditions variability and the of exposure patterns, which can be largely different during a working day, personal dosemeters use necessary obtain correct quantitative evaluation radiation dose absorbed by an exposed worker. Different classes exist and, among them, electronic polysulphone film dosemeters.
