International Journal of Advances in Life Science and Technology 2412-3803 2313-8335 International Journal of Advances in Life Science and Technology Testicular Doses of Patients Undergoing Radiological Examination of the Chest at Federal Medical Centre Makurdi, Nigeria International Journal of Advances in Life Science and Technology International Journal of Advances in Life Science and Technology 03-2014 2014 03-2014 03-2014 1 1 1 5 30 Nov 30 Nov The testicular dose of eight adult male patients undergoing radiological examination of the chest were investigated at the radiological department of the Federal Medical Center (FMC) Makurdi using themoluminescent dosimetry technique. The investigation was carried out using LiF TLD discs Reader, TLD model 4500 (Harshaw Radiation measurement product USA), 3-phase diagnostic X-ray machine and single a phase X-ray machine. The Mean testicular dose of the male patients investigated was found to be 0.0662±0.0034mGy. There is also a significant correlation between testicular dose and tube potential, in which higher tube potential delivered higher values of testicular doses. Results showed that, testicular doses are within acceptable limits, which is approximately 6.6% of the 1mGy reference dose level.
