Dose rate limitations of integrating survey meters for diagnostic x-ray surveys.
Medical and health physicists are often called upon to measure scatter and evaluate shielding for diagnostic x-ray installations. As exposure times are typically too short to allow rate meters to be successfully used, integrating survey meters are often employed. Pressurized survey meters are particularly valuable because of their increased sensitivity. In practice, some integrating survey meters may give erroneous results under typical measurement conditions.
