Criteria for performing multiple dosimetry

Abstract

When radiation fields vary spatially as a result of job- or location-specific conditions, the use of more than one dosimeter may be necessary for a variety of radiation protection purposes. This paper contains a methodology for when and how to use multiple dosimeters under conditions incident to routine activities in the presence of ionizing radiation. It also describes a methodology for determining the effective dose equivalent when the use of multiple dosimeters has been deemed necessary by radiation protection professionals. The methodology is based upon application of compartments and compartment factors. Included herein are examples demonstrating when multiple dosimeters should be used and how effective dose equivalent should be calculated using the compartment factors.
