Question

what X-rays of my teeth at the dentist show and why it has to be radioactive and what the heavy apron does

In: Physics

Answer 1

the x-rays show the root structure of the teeth; jaw bones / mandible; next set of teeth

all x-rays are radioactive – but its not a major concern unless you are constantly near them or getting them

the apron prevents the x-rays from going where you dont want them to go……getting exposed to the occasional x-ray is not harmful….but its also really easy to protect the areas where its not needed.
