Problems solved by technology

[0005] Using a uniform ellipsoid to represent the reference organism for dose rate estimation without distinguishing between tissues and organs not only ignores the difference between the ellipsoid and the actual body shape of the organism, but also affects the density of sensitive organs, element composition, nuclide distribution, and distribution in the body. dose rate effects due to location are also not taken into account, which would lead to uncertainty in estimates of dose rate to organisms and underestimation of radiation effects

Abstract

The invention relates to a simplified anatomical model establishment method for insect dose rate estimation, which belongs to the technical field of non-human species evaluation, and comprises the following steps: dissecting an insect sample to obtain each tissue / organ sample, and measuring appearance parameters and quality of each part of sample; detecting the density and the total element content of each part of sample; geometric description is carried out on each tissue / organ, a curved surface related to each part is determined, and a curved surface equation and a composition relation between the curved surfaces are given; establishing a Monte Carlo simplified anatomical model of the insect according to the curved surfaces determined in the step S3 and the curved surface composition relation of the parts; and estimating the insect dose rate by using the Monte Carlo simplified anatomical model of the insect. According to the method provided by the invention, a model which is closer to a real situation and is used for distinguishing tissues / organs can be provided for radiation influence evaluation of insects, and excessive protection in nuclear industry environment evaluation caused by conservative estimation is avoided.

Description

technical field [0001] The invention belongs to the technical field of evaluation of non-human species, in particular to a simplified anatomical model establishment method for insect dose rate estimation. Background technique [0002] As society attaches great importance to the protection of non-human species, the possible impact of ionizing radiation on non-human species has also received increasing attention. The International Atomic Energy Agency (IAEA), the United Nations Commission on Radiation Effects (UNSCEAR), and the International Commission on Radiological Protection (ICRP) have successively published special publications to discuss and describe this issue. [0003] International non-human species radiation dose and radiation effect assessment methods and models are: AECL approach from Canada, R&D128 and D-Max from the UK, LAKECOB from the Netherlands, ERICA from the EU, RESRAD-BIOTA from the US, EDEN2 from France, CATEAUR, etc., are currently the most widely used...
