What Can a Chest X-ray for a Health Certificate Detect?

A chest X-ray for a health certificate can check for abnormalities in the lungs, heart, mediastinum, and other areas of the body. It can also detect tuberculosis. This type of examination primarily utilizes X-rays to assist in diagnosing diseases, and it is a type of radiographic inspection that is harmful to the human body. Therefore, it is not recommended to frequently undergo chest X-rays unless necessary.

Yes, it is okay to undergo a chest X-ray for a health certificate during pregnancy preparation. However, it is best not to continue with pregnancy preparation after the chest X-ray is completed, as there is radiation involved in the examination, especially within a short period of time. There will be a certain amount of radiation present in the body. Therefore, from the perspective of eugenics, it is recommended to wait for at least three months after the examination before attempting to conceive, as this can reduce the risk of fetal malformations or spontaneous abortions.

1. Chest X-rays should not exceed one per year for routine physical examinations. Adults should not undergo more than one X-ray examination per year. For cancer prevention screenings in middle-aged and elderly individuals, it is advisable to limit the frequency to once per year or less.

2. Adolescents should not frequently undergo chest X-rays as exposure to X-rays may affect growth and development. Direct exposure to the lower abdomen and gonads can potentially lead to infertility later in life. Children's bone marrow is more susceptible to the risks of leukemia from radiation exposure compared to adults. Therefore, X-ray examinations should not be routinely included in adolescent physical examinations.

3. Pregnant women should avoid chest X-rays as much as possible. Exposure to X-rays during pregnancy may cause fetal malformations, intellectual disabilities, and defects in the hematopoietic and nervous systems in newborns. Therefore, it is best to avoid X-ray examinations during pregnancy unless absolutely necessary for diagnosing a medical condition. If necessary, the total number of X-ray examinations during pregnancy should not exceed two.

4. Wear protective equipment. If an X-ray examination is required for diagnostic or therapeutic purposes, lead protective gear should be worn. Non-exposed areas, especially sensitive areas such as the gonads and thyroid, should be shielded with protective equipment. Patients can actively request these measures from the doctor during the examination.

5. Stay away from the X-ray machine. When the X-ray machine is in operation, a warning light on the door of the radiography room will be illuminated. During this time, patients waiting for their examination should remain outside the protective door and avoid entering the examination room to minimize unnecessary radiation exposure.
