I guess your concern is about.is there is any risk in conceiving after radiation exposure....right.my straight forward answer is.NO, there is no risk in conceiving after radiation exposure. Let us discuss effect of radiation-radiation will having teratogenic effect(that means it causes chromosomal abnormalities in your baby) when u exposed it during early pregnancy(1-6wks). But it doesn't effect when u conceive after radiation exposure. U told me that you are not pregnant when u exposed with the radiation. So DON'T WORRY.RELAX, nothing will happen when u conceive in the future. I hope the above discussion is informative enough, useful and helpful for u.regards- Chat Doctor. .hopefully TWINS)last thing is that. don't be sorry for your English, I can understand your English very well. </s>
