X-ray Work Supervisor Pass is an unofficial multiple-choice question practice app specifically designed for studying for the X-ray Work Supervisor certification exam. It organizes information on X-ray management, relevant laws and regulations, X-ray measurement, and effects on living organisms in a format easily accessible for repeated study on a smartphone. No login or account creation is required.

This app contains 600 questions across four areas: 180 questions on X-ray management, 140 on relevant laws and regulations, 140 on measurement, and 140 on effects on living organisms. You can study at your own pace, from short practice sessions focusing on specific areas to comprehensive learning covering all areas.

The X-ray Work Supervisor certification exam tests knowledge not only of equipment and work management, but also on a wide range of topics including occupational safety and health laws, measurement concepts, and the effects of radiation on living organisms. Through practice questions, you can organize your knowledge in each area while distinguishing between similar terms and numerical conditions.

The practical exercises consist of 10 questions from each of the four areas, for a total of 40 questions. This app allows you to comprehensively review the knowledge you've acquired in each subject area, using a fixed distribution that reflects the subject structure of the actual exam. After each exercise, you can check the number of correct answers, the number of responses, and the correct answer rate, and then return to the explanations for review.

For each question, you can check whether your answer is correct or incorrect and the key points after answering. Detailed explanations provide background knowledge and points to check, while the explanations for each option show why each of the four options is correct or incorrect. This allows you to review not just by memorizing the correct answer, but also by organizing easily confused ways of thinking.

Incorrect answers are recorded in your learning history, which can be used to prioritize reviewing those incorrect answers. The analysis screen allows you to check your correct answer rate and learning progress by subject area. By identifying your weak areas and using them in subsequent exercises, you can create a learning and review cycle. You can also adjust the font size, learning subject area, and explanation display settings.
