BERT (Background Equivalent Radiation Time) values are designed to provide a way to communicate patient dose in a manner that is easier for patients to understand. Specifically, these values compare the amount of radiation a patient receives during a radiological procedure with the length of time they would need to be exposed to natural background radiation to receive the same dose. This comparison links medical exposure to natural environmental radiation in a familiar context, which can help alleviate patient concerns regarding radiation exposure.

This method offers a relatable understanding of radiation, allowing individuals to gauge their exposure in terms of something that is part of their daily lives—background radiation. Since many patients may have difficulty grasping numerical dose values, BERT effectively contextualizes the information by translating it into equivalent durations of natural background exposure. This aspect makes BERT particularly valuable in patient communication within the medical imaging field.
