Anew method for measuring radioactive methane is an optical one based on spectroscopy. Previously, radioactive methane has been measured with accelerator mass spectrometry involving expensive machines. Optical measuring could be a cheaper and more agile method.

Researchers have developed a new technique that assesses radiation exposure in about an hour using an insulator material found in most modern electronics. The technique can be used to triage medical cases in the event of a radiological disaster.

NASA’s Glenn Research Center has devised an efficient new method of combining primary and secondary signals with minimal loss and noise. With its ability to reduce system noise, this novel signal combiner delivers the best opportunity to receive a desired signal not easily distinguished from background...

A transparent test patch, printed with harmless molecules, signals food contamination as it happens. The patch can be incorporated directly into food packaging, where it can monitor the contents for harmful pathogens such as E. coli and Salmonella. The new technology has the potential to replace...

In many applications, such as remote sensing of atmospheric trace gases, monochromatic radiation with multiple discrete wavelengths is required. To date, there no instrument or technique that measures the wavelength jitters and fluctuations in real time.
