Abstract:: Abstract: Objective To reduce the radiation dose of the thyroid and mammary gland induced by the scattered radiation in digital mammography using protective clothing, and to investigate the protective effect of protective clothing. Methods Thirty patients who underwent digital mammography were randomly enrolled in this study. The newly-developed 0.5 mm Pb lead rubber protective clothing was used to reduce the radiation dose of the thyroid and mammary gland. A set of LiF (Mg·Cu·P) thermoluminescence dosimeters was placed at the inside and outside of protective clothing. After the radiation under the same detection condition, the air kerma of the inside and outside the protective clothing were acquired by LiF (Mg·Cu·P) thermoluminescence dosimeters. Results Statistical difference was found in the air kermas of the inside and outside of the protective clothing (P<0.05). The protective effects of protective clothing for the thyroid and mammary gland reached (99.25±0.99)% and (99.17±1.03)%, respectively. Conclusion Using protective clothing for the protection of the thyroid and mammary gland can reduce the scattered radiation in digital mammography, with a remarkable protective effect.
