Deep Space: The new frontier of radiation controls
In commercial nuclear power, there has always been a deliberate tension between the regulator and the utility owner. The regulator fundamentally exists to protect the worker, and the utility, to make a profit. It is a win-win balance.
From the U.S. nuclear industry has emerged a brilliantly successful occupational nuclear safety record—largely the result of an ALARA (as low as reasonably achievable) process that has driven exposure rates down to what only a decade ago would have been considered unthinkable. In the U.S. nuclear industry, the system has accomplished an excellent, nearly seamless process that succeeds to the benefit of both employee and utility owner.

Several neutron radiography experiments were done at the Neutron Radiography Reactor facility, Argonne National Laboratory, Idaho Falls, Idaho. Square samples of cadmium were exposed to collimated neutrons (L/D = 185 and 300) to determine the width of the squares. Two methods of analysis, the arctangent fitting technique and the differential smoothing technique, were applied to data produced by microdensitometer measurements of several types of film. The results were compared for accuracy and precision with a carefully calibrated measurement of the samples. From the mathematical analysis a resolution parameter is obtained that might serve as a facility calibration parameter.
