The annual mean ± SD effective dose (range) to the physicians, nurses, and radiologic technologists using two badges was 3.00 ± 1.50 (0.84–6.17), 1.34 ± 0.55 (0.70–2.20), and 0.60 ± 0.48 (0.02–1.43) mSv/y, respectively. Similarly, the annual mean ± SD dose equivalent range was 19.84 ± 12.45 (7.0–48.5), 4.73 ± 0.72 (3.9–6.2), and 1.30 ± 1.00 (0.2–2.7) mSv/y, respectively. The mean ± SD effective dose for the physicians was 1.02 ± 0.74 and 3.00 ± 1.50 mSv/y for the one- and two-badge methods, respectively (p< 0.001). Similarly, the mean ± SD effective dose for the nurses (p = 0.186) and radiologic technologists (p= 0.726) tended to be lower using the one-badge method
