found: EPA Office of Solid Waste and Emergency Response WWW site, Mar. 15, 2006(Many field devices that measure external gamma radiation, such as continuous radon monitors and high pressure ionization chambers, provide a real-time continuous record of radiation exposure levels and radionuclide concentrations. Such devices are useful for determining the temporal variation of radiation levels at a contaminated site and for comparing these results to the variability observed at background locations)
