| Surprisingly, x rays do not penetrate Earth's atmosphere, so astronomers must place x-ray telescopes in space. |
| To measure body fatness, one may use dual energy x-ray absorptiometry, densitrometry or bioelectrical impedance. |
| In the radiotherapeutic range, high-energy electron beams penetrate less than high-energy x-ray beams. |
| The easiest way to avoid radiation is to absorb it, like wearing a lead apron when you get an x-ray at the dentist. |
| The denture had no metal claps and could not be radiographically detected as acrylic is radiolucent and cannot be detected on x-ray film. |
| An x-ray is taken postoperatively to verify that the acetabulum is corrected and the acetabular fragment is secured with cortical screws. |
