According to Article 22 of the Measures for the Administration of Safety Protection of Radioisotopes and Radiation Devices, the personnel who have obtained the certificate of radiation safety training shall receive retraining once every four years.

Radiation safety retraining includes newly promulgated laws and regulations, professional standards and technical specifications related to radiation safety and protection, as well as case analysis and experience feedback of radiation accidents. Those who have not participated in retraining or failed the retraining examination will lose their radiation safety training certificate automatically.

(1) Carefully examine the questions and specify the requirements.

A key step in taking any exam is to read the exam requirements repeatedly and check the questions carefully before answering them.

(2) Easy before difficult, grasp the order.

Generally, the arrangement of test paper topics is trapezoidal in difficulty, from easy to difficult. There are more basic knowledge topics in the front and more comprehensive topics in the back. After reading through the examination paper, do the questions you think you are sure of first, so that you can make rational use of your time.

(3) the handwriting is neat and the format is correct

The paper should be written neatly and clearly. If the handwriting is scrawled, it is easy for the examiner to read it clearly, and the paper is untidy and it is easy to lose this part of the score.
