Why is there no effective real-time Continuous Radiation Monitoring System?
Japan's disaster has raised many questions regarding safety of the public. It has served as a wakeup call to the agencies tasked with protecting the public. Not least of these questions, but certainly the most far-reaching is the question of the safety of nuclear power and radiation contamination of air and water. Way back when nuclear power was first established, in the 1960s public opinion was ...

Application of modified Arxula adeninivorans yeast cells in an online biosensor for the detection of estrogenic compounds in wastewater samples
Abstract The ‘EstraMonitor’ was developed to provide an automated system for the detection of estrogenic compounds. It can be used for semi-online and continuous monitoring without additional instrumentation. Previously it was used to detect pure estrogenic molecules. In this investigation, the ‘EstraMonitor’ is used to detect the estrogenic activity in five non-pretreated ...

Increased Demand for PureAire’s Oxygen Monitor for Nitrogen and Helium Storage
When storing or using Liquid Nitrogen, Helium, CO2, or Argon cylinders in a confined space, what are the potential risks? Gas leaks are the most common, requiring the need for an oxygen deficiency monitor for protecting employees in the workplace. With inert cryogenic gases, loose or broken fittings can leak gas into a room displacing oxygen, causing impaired judgment or loss of life to workers. ...

Level - what is Capacitance?
An electrical parameter which physically is most easy to define, electrically often misconstrued. Physically, a capacitor is two electrical conductors separated by a non-conducting (or very high resistance) medium between the conductors. Consider the two plates of area (A) in Figure 1. The plates are metallic and they are separated by a distance (D). Figure 1. C=KA/D If we fill the space ...

Double benefit of monitoring Indoor Air Quality (IAQ)
It is a difficult balance to save money and energy yet maintain a comfortable and healthy indoor air environment. A logical solution to controlling indoor air pollution is good ventilation coupled with IAQ monitoring using gas sensors. This can ensure healthy indoor air as well as a more efficient HVAC system. Typical IAQ investigation and examination consists of taking single-point ...

Online monitoring of algae concentration with ALGcontrol - Case Study
Online monitoring of algae concentration with ALGcontrol The presence of algae in surface waters is a potential threat to the quality and ecology of the water system. The control and monitoring of the algae concentrations are therefore of high importance. Due to green algae problems in the water reservoir of a drinking water treatment plant, the ALGcontrol was installed to continuously monitor ...

What is EC in water ?
IntroductionEC or Electrical Conductivity of water is its ability to conduct an electric current. We have a special water EC detector to detect the EC content. Salts or other chemicals that dissolve in water can break down into positively and negatively charged ions. These free ions in the water conduct electricity, so the water electrical conductivity depends on the concentration of ions. ...
