Foreign scientists develop the first portable atomic radiation monitor

Brad Jones, a professor of chemistry from Wake Forest, is leading a team of scientists from four different research institutes to develop the first portable atomic radiation monitor that detects and identifies radioactive particles from contaminated areas. The device will allow rapid detection of dust, dirt, water and plants in the event of a terrorist attack such as a "dirty bomb".
The three-year project was supported by the National Natural Science Foundation and the Department of Homeland Security, and they hope scientists will make recommendations for radiological monitoring devices. Jones, who specializes in the manufacture of spectroscopic equipment, therefore proposed a design that was used to test lead levels in blood samples several years ago.
Jones' "Tungsten Coil Atomic Emission Spectrometer" utilizes a wire in a standard projector bulb driven by a 12 volt battery. The suspected environmental sample is dissolved in the liquid and the droplet is placed on the coil. The sample was dried in a low pressure environment and then the residue was evaporated at 3000 degrees to produce a flash. Each metal has a unique color that is collected by the fiber optic sensor into the notebook. The test results are finally presented as icons showing the wavelength and intensity of each sample, allowing scientists to identify specific elements and radiation doses.
In addition, the technology may be used to test for contamination from pesticides and other contaminants. Instrument manufacturer Teledyne Leeman Labs is currently interested in manufacturing and promoting Jones' equipment.
