Objectives : X-rays used in medical diagnosis contribute a major share to population doses from man-made sources of radiation. This paper attempts to measure the patient and organ doses in patients undergoing some special procedures involving fluoroscopy.Materials and Methods : Radiation doses received by 93 patients undergoing five special procedures (Barium Swallow, Barium Meal, Barium Enema, IVP and myelograms) were measured with CaSO4-Dy thermo luminescent dosimeters following standard TLD Procedures. Doses to critical organs like ovary, testes and thyroid were estimated by applying suitable correction factors. Result : The study revealed a maximum surface dose 75.92 mSv for barium meal study. The ovary doses were significant for Barium meal enema, and myelograms. Conclusion : The dose levels as measured by this study were significant but not alarming. Attempts could be made to lower the doses received during these procedures.
