Where is a film badge typically worn by the operator?

A film badge is typically worn at waist level because this placement helps ensure that the dose of ionizing radiation received by the operator is monitored accurately. The waist area is generally representative of the exposure the worker may receive during their regular duties, especially in a dental radiography setting where certain procedures can involve exposure to x-rays.

Wearing the badge at waist level helps to prevent it from being affected by scatter radiation that may be more intense in other areas, such as the head, and ensures that it consistently measures the operator's occupational exposure, aligning with safety protocols and regulatory requirements meant to protect dental professionals from excessive radiation exposure.
