Mammography is the radiographic examination of the breast. Radiation doses and cancer risks from breast imaging studies is under scrutiny hence, the need to investigate the dose received during mammography. Objective of the study: To determine the doses received during mammography in two university teaching hospitals and to compare it with other established work. Methodology: This study is a prospective cross-sectional study conducted in two university teaching hospitals in North eastern

Thermoluminiscent dosimeter (TLD) chips were exposed for cranio-caudal and medio-lateral examinations to record the entrance skin dose (ESD). TLD readings were obtained at the Centre for Energy Research and Training Zaria, Kaduna state, Nigeria. Dance formula was used to convert ESD to mean glandular dose (MGD). Student T-test was used to determine the relationship between the mean ESD obtained in the two centers and Pearson's correlation was used to determine the relationship between the MGD and anthropotechnical parameters. Statistical significance was set at P<0.05. Results: The total MGD for this study was 0.31±0.05mGy and 0.69±0.11 mGy for cranio-caudal (CC) and medio-lateral oblique (MLO) respectively. Conclusion: Mean Glandular doses were lesser than recommended standards. There was no statistical significant relationship (p>0.05) between the MGD and anthropotechnical parameters.
