Introduction

X-rays are electromagnetic waves with extremely short wavelengths and high energy, and their wavelengths are shorter than those of visible light. As five routine detection methods One, X-ray detection has been widely used in industrial non-destructive testing. Because of its strong penetration, it will cause certain damage to the body of the inspector. The safety protection problem in this X-ray inspection has received extensive attention. GB /Z 41476 aims to establish protection requirements for X-ray equipment below 1MV And personnel safety protection rules, it is proposed to be composed of 4 parts. --- Part 1.General safety technical requirements. The purpose is to give the dose limit for personnel in the operation of X-ray equipment below 1MV, Equipment usage requirements, etc. --- Part 2.Technical requirements for protection. The purpose is to provide effective, Reliable radiation protection measures. --- Part 3.Calculation formulas and charts for radiation protection of X-ray equipment below 450kV. The purpose is to give below 405kV The calculation formulas and related charts of the main technical indicators of X-ray equipment protection are convenient for the calculation of relevant data in the process of X-ray protection. --- Part 4.Calculation of the control area. The purpose is to provide a calculation method for the control area of X-ray equipment below 1MV, and for the third Some content is further supplemented. Non-destructive testing equipment X-ray below 1MV Radiation Protection Regulations for Equipment Part 1. General safety technical requirements
