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.

Calculations of the ionization density resulting from β-ray fluxes produced by the decay of UX2 (Pa234m) using constant-cross-section transport theory agree with experiment to better than 5%. The ionization densities were measured using an extrapolation chamber and a thin-walled ionization chamber. The experimental β-ray absorption coefficients reported in 1931 by the International Radium-Standards Commission can be calculated to better than 15% using the same theory.
