title: A new method of estimation of dose conversion coefficients for aquatic biota.
abstract: In order to develop the basis of an approach, through which we can comprehend the relationships of radiation exposures and dose, and dose and radiological effects, large numbers of dosimetric data are required. It is complex to estimate the dosimetry involved due to enormous variability of organism shapes, masses, and their natural habitats. This paper aims to develop an empirical equation, which correlates dose conversion coefficients (DCCs) with organism volume V, density ρ, source energy E and curve fitting coefficients. Compared with the values calculated by a Monte Carlo method, the mean relative deviation of the empirical-fitted DCCs are reasonably low for gamma external exposure and beta internal exposure. The empirical-fitted values are very close to those calculated using a simplified anatomical phantom, the ERICA Tool or a voxel phantom.
