In this work, the Thermoluminescence Dosimetry (TLD) technique was used with phantoms to measure the amount of radiation received by patients during routine Posterior-anterior (PA) chest X ray examination in Federal Medical Centre and Bishop Murray Hospital Makurdi, The results obtained were compared with the diagnostic reference level set by International Atomic Energy Agency (IAEA) and International Commission for Radiological Protection (ICRP). At Federal Medical Centre, twenty eight TLDs were exposed and the average skin dose measured was 0.152 ± 0.01mGy. For Bishop Murray Hospital, nine measurements were carried out and the average skin dose measured was 4.207 ± 0.5mGy. The skin dose measured at Federal Medical Centre, Makurdi is found to be within safe radiation dose limit for patients as well as members of the general public. For Bishop Murray Hospitals, the mean dose measured was above the recommended dose by ICRP both for patients and members of the public.
