You can use the mobile X-ray machine used in orthopedic treatment, which will produce a small amount of rays. So you don't have to worry. The perspective Kv is set at the maximum of 5.0Kv, and you used 2.2Kv, which is within the normal range.
In addition, you are wearing lead clothes, so the amount of radiation received should be relatively small, but 8 minutes and 46 seconds of irradiation, if it is continuous irradiation, the time is a bit long, if it is intermittent irradiation, it is better.
There must be some influence. Mobile X-ray machine is mainly aimed at bone injury. It is convenient and quick to use, and it can promote the operating room, so the impact is inevitable. But I can tell you for sure that the impact is relatively small.
Shanghai Medical Device Factory has merged with China Resources Wandong Medical Devices, which is called China Resources Shangxie. The X-ray machines produced are of high level in China, so you can use them with confidence.
Please ask questions if you have any questions.
