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.

One of the advantages of radioisotope x-ray techniques is the potential for using primary radiation, which has enough energy to excite K x rays of even the heaviest elements. In using these penetrating x rays in the analysis, the effects of some of the most severe sources of error in x-ray techniques are less significant than when using softer L x rays. This paper theoretically illustrates the advantages of isotope-excited K x-ray determinations of heavy elements and describes some feasibility studies and applications as determination of lead in zinc and tungsten in mineral samples.
