Dosimetry and process control for radiation processing of bulk quantities of particulate foods

Abstract

Radiation processing of particulate foods in bulk quantities requires the determination of dose distributions. Due to variable flow patterns, miniature dose meters must be suspended in a reproducible and representative manner in the stream of food particles. It is also desirable that the material used for dosimetry be non-toxic and not foreign to food. Food components such as amino acids, or inert materials like quartz, would be acceptable. The dosimetric properties of some such materials are described and results from measurements in a pilot plant are presented.
