Absorbed dose rate for marine biota due to the oil spilled using ICRP reference animal and Monte Carlo simulation

Appl Radiat Isot. 2022 Oct:188:110354. doi: 10.1016/j.apradiso.2022.110354. Epub 2022 Jul 5.

Abstract

The current study aimed to obtain dose conversion coefficients for marine animals due to an oil spill accident using two variables: crude oil activity concentration and organism depth. Thorium series presented a dose contribution twice that uranium series for similar conditions. Bi-214 and Tl-208 stood out for delivering a higher dose rate for uranium and thorium series, respectively. Results obtained can be used to assess the maximum exposure time for emergency oil control, removal, and mitigation in an oil spill accident.
