Abstract: Radiological dose rate from X-rays produced by a reltron (relativistic electron tube) microwave tube are calculated via standard electron-photon Monte Carlo transport software from the Integrated TIGER* Series developed by Sandia National Laboratories, Albuquerque,NM. Comparison of an extrapolation of this dose rate for several hypothetical thickness of lead shielding surrounding this reltron with the standard maximum worker-allowed radiation level predicts the thickness of lead shielding required in the design of the reltron. Using worst case modeling for the X-rays, the required amount of lead shielding is, roughly, 1 ton.
