A method of evaluating the photoneutron fluence in the maze of accelerator facilities due to room scattered neutrons is presented. Measurements were made to demonstrate that the room scattered fluence is reduced by a factor of 2pi in going from the t

The problem of calculating the neutron capture gamma-ray dose rate due to thermal neutron capture in a boron or cadmium rectangular shield is considered. An example is given for shielding for a door at the exit of medical accelerator room maze in ord

The photon response of silicon-diode neutron detectors is analyzed theoretically and measured in the 15-25-MeV region. The main mechanism for producing a response in the diode is shown to be the displacement of silicon atoms by scattering of electron

The radial and longitudinal development of electron-photon showers has been measured in copper and lead at 1 GeV. A new technique using the thermoluminescent property of LiF has been employed to measure energy deposition. The resultant radial distrib

The Hansen readout system for the multi-channel Hutchinson-Scarrott pulse height analyzers is modified to an automatic printout system. The actual printout speed depends on the number of counts stored in the channels. With all channels empty, the pri

A semiempirical analytic description of the accelerator depth-dose curve is described along with its physical explanation. The results of Monte Carlo calculations are presented and compared with experimental data to test this model. Calculations were
