ON RESIDUAL DOSE-RATE WITHIN PARTICLE ACCELERATOR ENCLOSURES

A mathematical proof of a theorem concerning the flux density of parti cles at any point interior to a simple closed convex surface in which the surface emits such particles uniformly and isotropically is presen ted. The relationship of this theorem, which is of rather general vali dity, to related observations of other workers is discussed. The ramif ications of the theorem are considered with particular attention devot ed to conditions commonly found at particle accelerators. It is conclu ded that results of this theorem are directly applicable to efforts to apply the principle of maintaining dose equivalents received by perso nnel as low as reasonably achievable.
