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.

Increasing emphasis is being placed on the quantitative aspects of neutron radiography as an aid in characterizing reactor fuel specimens nondestructively. In general, precise dimensioning from radiographs requires some aid to remove subjectivity from film interpretation; photographic image enhancement was the aid used in this study. The fundamental limitation in determining physical dimensions from radiographs is shown to be related to the ability of the neutrons in the inspection beam to penetrate the samples. Neutron penetration is dependent on parameters other than physical size, so it is reasonable to expect differences between physical dimensions and dimensions derived from radiographs.
