Polysulphone has been widely used as a dosimeter to quantify personal solar UV exposures to humans during normal daily activities. In summer at sub-tropical and tropical latitudes, the dynamic range for UV exposures allows the use of the polysulphone to measure solar UV over periods of approximately three to six hours. The use of mesh as a filter over the polysulphone has been previously report...

Spectrophotometric measurements of the Fricke–gelatin–xylenol orange (FGX) gel dosimeter demonstrated reproducible linear dose response up to 25Gy. However, oxidation processes continue post-irradiation, affecting the response of this dosimetry system. Additional oxygenation during preparation increases the sensitivity of the gel but does not improve the auto-oxidation stability of the dosimete...

AIM This study was conducted to evaluate and compare the tissue reactivity and suture handling characteristics of chromic gut, silk, and 'jimat' suture materials in cat thigh muscle. MATERIALS AND METHODS This experimental study was conducted from November, 2013 to April, 2014 in Kombolcha Animal Diseases Survey, Research and Diagnostic Laboratory, Kombolcha, Ethiopia. A total of 36 local bre...

In recent years, interest in personal noise exposure has expanded beyond a workplace safety measure to become an effective means of investigating physiological effects of the acoustic environment on an individual. This work investigates the effects of the wearer's voice as a possible dominant sound source on body-mounted noise dosimeters and develops methods to improve the application of dosime...
