Rapid In-Situ Effective Dose Equivalent Measurement Using the Superheated-Liquid-Droplet Technique

Abstract

This study performs a rapid in-situ effective dose equivalent evaluation using SLD. The effective dose equivalent recommended by ICRP-26 allows the direct calculation of the primary personnel limiting quantity by measuring the dose equivalent in various internal organs or tissues. Therefore, an indigenous multislab phantom coupled with the SLD multicounting system is set up to evaluate the effective dose equivalent, HE. Moreover, MCNP computational results are also compared. Comparisons indicate that underestimation of practical evaluations (within −15%) may be largely attributed to the insensitive nature of SLD in measuring the γ-ray induced dose.
