Abstract: Several salient issues about the estimation and management for public dose of gamma irradiation facilities were discussed in this article to optimize the dose estimation and management and reduce operational costs. Inappropriate estimation and management would lead to elevated operational costs and conflicts between the regulatory authority and the licensee. In some cases, in troduction of a third team, concrete analysis of public exposure and facility operation, and installation of isolated areas are helpful to the supervision and project operation under the premise that the public and environment are sufficiently protected.
