A mother brings her child in for his first routine visit. The child is 5 years old and has already gotten his 6-year-old molars. The dentist likes to have radiographs taken on children at their first dental visits to get close-up readings of their teeth and gums to help diagnose any problems early in their development. The mother does not like the idea of exposing her child to radiation at such a young age, but she agrees with the condition that she must be in the room. The child is situated in the chair, and the backrest and headrest are adjusted to make the patient as comfortable as possible to minimize movement during exposure. The radiographs show darkening between the molar and cuspid on the right side of the mouth.How far away from the child should the mother be when the radiographs are administered?
