PATHWAY-II: A Computer Code for Radiological Environmental Pathways Analysis

Abstract

This paper describes the code PATHWAY-II used for calculating radiation doses following acute or chronic releases from a nuclear facility. The code allows analysis of a wide variety of pathways via the atmosphere or surface water to any of several possible dose recipients. The methodology employed is based on draft Canadian


Standards CSA N288.1 and CSA N288.2. Written in Compiled BASIC for microcomputer operation, the code consists of a series of eight integrated modules and associated data files. PATHWAY-II is a very useful tool for performing environmental radiation dose assessments.
