Computational Phantoms of the ICRP Reference Male and Reference Female
Computational models of the human body – together with radiation transport codes – have been used for the evaluation of organ dose conversion coefficients in occupational, medical and environmental radiation protection. During the last two decades, it has become common practice to use voxel models that are derived mostly from (whole body) medical image data of real persons instead of the older ...
متن کاملOrgan doses from environmental exposures calculated using the ICRP Reference Male and Reference Female voxel phantoms
In its recent recommendations the ICRP adopted two voxel models of an adult male and an adult female to be used for the forthcoming update of organ dose conversion coefficients. These voxel models are representative of an average population, i.e. they resemble the ICRP reference anatomical data with respect to their external dimensions and their organ masses and were constructed for this purpos...
متن کاملAbsorbed dose rate conversion coefficients for reference terrestrial biota for external photon and internal exposures.
The paper describes dosimetric models that allow the estimation of average radiation exposures to terrestrial biota due to environmental sources in the soil as well as internal uniform distributions of radionuclides. Simple three-dimensional phantoms for 13 faunal reference organisms are specified. The calculation of absorbed dose per unit source strength for these targets is based on photon an...

For 79 % of the radiopharmaceuticals, the new calculations gave a lower effective dose per unit administered activity than earlier estimated.” Should be “For 63 % of the radiopharmaceuticals, the new calculations gave a lower effective dose per unit administered activity than earlier estimated.” 2. “As a mean for all radiopharmaceuticals, the effective dose was 25 % lower.” Should be“As a me...
متن کاملEffective dose to adult patients from 338 radiopharmaceuticals estimated using ICRP biokinetic data, ICRP/ICRU computational reference phantoms and ICRP 2007 tissue weighting factors
BACKGROUND Effective dose represents the potential risk to a population of stochastic effects of ionizing radiation (mainly lethal cancer). In recent years, there have been a number of revisions and updates influencing the way to estimate the effective dose. The aim of this work was to recalculate the effective dose values for the 338 different radiopharmaceuticals previously published by the I...
