There have been numerous threads on this topic. Long story short, of course, yes - BUT absent any information on how much the exposure is, odds are, you did not get enough or not enough time has passed to even think about risk. The risk is pretty small for radiation given in testing - such as a CT scan.
Sunshine (which you need for vitamin d!), and even riding on an airplane exposes you to radiation - so everyday, it is a factor in life - a small one.
Live a healthy life and enjoy!
my son had radiation on his cancerous brain tumour he has had no cancer for 18 yrs
