In brief: No
Radiation poisoning occurs at exposures of 1000 msv and greater ( http://sgoti.

In brief: No
No, the radiation has a short half life and is essentially completely out of the system in 24 to 36 hours.

I agree but do not forget that radiation adds up so that if you get many xrays in your lifetime, the risk of cancer increases. That is not the same as radiation poisoning but there is a risk of radiation related to every x-ray you get. Some of the tests that we do expose you to much more radiation than a simple chest xray for instance.
