> Now, according to a report in New Scientist, Joseph Farmer and colleagues
> at the Lawrence Livermore National Laboratory in California have produced a
> new detector sensitive even to low levels of gamma radiation.
> Their device is set to speed up screening times.
> It doesn’t directly detect gamma rays themselves, but instead looks for the
> hydrogen peroxide generated when the rays interact with water.
> The detector consists of an “electronic nose” chip coated with a thin layer
> of water that is condensed onto its surface. When gamma rays strike water
> molecules in that layer, the nose chip detects any hydrogen peroxide formed.
> According to the inventors, as well as being more sensitive, their design
> can pick up a wider range of gamma ray energies than conventional
> detectors. (ANI)
