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 new approach is described in the use of NE-213 detectors to perform neutron spectra measurements, which have been developed jointly by the U.S. Naval Academy and the Naval Surface Weapons Center. The approach is based on collecting a three-dimensional matrix of neutron and gamma-ray data. The dimensional plots of the collected data, which are computer generated, are used to ensure proper separation of the neutrons from gamma rays. After separation, the spectra are calibrated, binned, renormalized, and finally unfolded. In this manner neutron energy spectra and kerma are obtained. Linear attenuation coefficients for 14-MeV neutrons were determined by placing iron, lead, aluminum, polyester, and polyethylene-based materials between the neutron source and the NE-213 detector.
