Which of the following is a common method for monitoring radiation exposure among workers?

Personal dosimeters are widely used in the field of radiation safety to monitor the exposure of workers to ionizing radiation. These devices, often worn on the body, measure the amount of radiation that a worker receives over time and provide a direct indication of their exposure levels. Personal dosimeters come in various forms, including film badges, thermoluminescent dosimeters (TLDs), and electronic dosimeters, and are essential for ensuring that exposure stays within regulated limits.

Biological assays measure effects or changes in biological systems due to radiation exposure but are typically not used as a routine method for monitoring individual radiation exposure on a daily basis. Regular physical exams can assess general health but do not specifically quantify radiation exposure. Occupational health records document the overall health and any incidents related to workplace exposures but are not a direct monitoring method like personal dosimeters. Therefore, personal dosimeters are the most effective and widely adopted tool for monitoring radiation exposure among workers in environments where radiation is present.
