Is there radiation in the chest X-ray car passing by for medical examination? Is there a lead plate protection on the chest X-ray car?

First of all, the chest X-ray car is shielded and will not leak. You can rest assured that the inspection in this respect is quite strict.

Secondly, it doesn't matter even if you have a chest X-ray. The radiation dose of chest X-ray is only 0.03mSv, and it doesn't matter if it is done three or four times a year. What's more, you just pass by the chest X-ray car, so there is no problem.

So, please rest assured that it won't affect you, not as much as your mobile phone.

I wish you good health
