I had Hashimoto a year ago?

I had Hashimoto a year ago and thyroid function has returned to normal without medication. My doctor suggested a neck xray for an unrelated condition but I am worried about the radiation directly on the thyroid. Should I avoid the xray due to risk of harming my thyroid further?

Age: 51
Female
Medications: None
General Information: My doctor says the radiation level in a neck xray is small and won’t hurt my thyroid but with the history of Hashimoto, I’m concerned. Thoughts?
