Abstract

The invention provides a method for calculating the radiation sensitive part displacement absorption dose based on absorption dose depth distribution, and belongs to the technical field of space environment effect, nuclear science and application. The method includes selecting a material with known one-dimensional displacement absorption dose depth distribution, converting the displacement absorption dose depth distribution into the absorption dose equivalent thickness distribution; performing the area division on the structure where the radiation sensitive part is located, determining the types of materials in each region and the thickness of each material; and then converting the thickness of the material in each region into the equivalent thickness, determining the absorption dose of each equivalent thickness and the one-way absorption dose, and finally, calculating and obtaining the displacement absorption dose of the sensitive part in the structure. The problems that a radiation sensitive part of the prior art is complex in displacement absorption dose calculation and long in time consumption are solved. The method can be used for rapidly evaluating the displacement absorptiondose of complex structures such as a spacecraft.

Description

technical field

[0001] The invention relates to a method for calculating the displacement absorbed dose of a radiation-sensitive part, and belongs to the technical fields of space environment effect, nuclear science and application. Background technique

[0002] Absorbed dose refers to the energy absorbed by a unit mass of material after being irradiated. The strict definition of absorbed dose is the quotient obtained by dividing the average energy dE given by radiation to a material with a mass of dm divided by dm. It is represented by the symbol D and the unit is Gray ( Gy). Spacecraft orbiting in space will be affected by various environmental factors, such as particle radiation, microgravity, and atomic oxygen. With the rapid development of electronic technology, the application of electronic components is becoming more and more extensive. Electronic devices are widely used in satellites, spacecraft and space shuttles to achieve various functions. For electronic devic...
