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.

This article establishes a physical model of the interaction between a surface electron beam and the plasma with a transverse magnetic field. The dispersion relation of the beam-plasma interaction is derived by using the field matching method. The effects of magnetic field, electron beam electron density, and plasma density on the radiation frequency and z-direction wave vector are studied. The results indicate that the stronger the transverse magnetic field is, the higher is the cutoff frequency of plasma radiation. The higher the plasma density or electron beam electron density is, the higher are the corresponding radiation frequency and radiation wave number.
