Radiation safety at a neutron generator

The Naval Research Laboratory has a number of accelerators capable of producing neutrons with their attendant neutron radiation safety problems. These include a 66 MeV Linac, a 55 MeV Cyclotron, a 5 MeV Van de Graaff and a Kaman Neutron generator. Since the radiation safety problems which occur at a neutron generator are common to all these machines we will discuss all of them as a class of machines called neutron producing accelerators. These machines at NRL produce neutron fluxes up to 10/sup 14/ neutrons per second (Linac) with energies up to 40 MeV (Cyclotron). Neutron producing accelerators present special radiation safety problems which can roughly be divided into two categories: Measurement and control of the neutron field and measurement and control of the activation products left after the machine is turned off. This paper outlines some of the problems encountered and some of the steps taken to ''solve'' these problems at NRL.
