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.

A manganese sulphate bath technique has been used to make an accurate measurement of the 9Be (n, 2n) cross section averaged over a pure 252Cf spontaneous fission-neutron spectrum. Monte Carlo calculations were performed to correct precisely for spectrum distortion due to elastic scattering in the beryllium. Corrections were also made for all other competing reactions of importance. The result obtained, 144 ± 6 mb, is in good agreement with the value of 150 mb calculated from an excitation curve based on the latest available differential data.
