  • The basics of polarization (animated) | Spectroscopy Guides

    In many spectroscopic and photonics applications, it is desirable to work with light that has been polarized in a particular direction. In this article we explore what polarization is, and how it may be obtained from an unpolarized light source. Electro-magnetic radiation (light) What we generally refer to as “light” is more correctly known as 'electromagnetic ...

  • How to treat radioactive NORM sludge with VacuDry

    NORM doesn’t sound like a big thing. But Naturally Occurring Radioactive Material might let the alarm bells ring. Everyone has heard of “radioactive material” and that sounds dangerous. However, most of this material is trapped deep in the ground beneath our feet. From there it reaches the surface, for example via the water cycle. Another possible pathway for NORM to reach the ...

  • Optimisation of radiolysis of Reactive Red 120 dye in aqueous solution using ionising 60Co gamma radiation by response surface methodology

    In recent years, employing radiation technology is gaining great interest in degradation of industrial effluents. In this work the possibility of using gamma irradiation to degrade Reactive Red 120 (C.I.292775) was explored. The effects of pH, dose of gamma irradiation and concentration of dye were examined and their interaction were also established based on their response. For the analysis ...
