“…The DRLs are measured by placing a thermoluminescent dosimeter (TLD) on the patient's entrance skin, thereby measuring the entrance surface dose. In first-world countries with advanced medical systems, guidelines for medical exposures and clinical applications have been established many years ago [18,19]. To the best of the researchers' knowledge, there is no evidence that any study evaluated the radiation exposure to the thyroid gland in pediatric chest x-rays in Nigeria.…”

The study aims at measuring the entrance surface dose (ESD) of the thyroid gland of infant patients undergoing anterior-posterior (AP) chest x-ray in Usmanu Danfodiyo University Teaching Hospital Sokoto (UDUTHS). The study further determines the effective dose to the thyroid on infant patients undergoing AP chest x-ray. Also, compare the entrance surface dose of infant patients obtained from the study with other similar studies and diagnostic reference levels (DRLs) recommended by the International Commission on Radiological Protection ICRP. This is a prospective cross-sectional study and the primary source of data was obtained. Pediatric patients used for the study who are referred to the radiology department for an anteroposterior chest x-ray, UDUTH, Sokoto state, Nigeria. A non-probability sampling technique was adopted for the patient who came in for a chest x-ray (AP) and as recommended by ICRP that a minimum of 10 patients should be used to determine the ESD for each projection, therefore 15 patients were adopted for this study. The result of the ESD obtained for the thyroid on infant patients undergoing chest x-ray (AP) was averaged and the mean of the ESD was 1.38 mGy. This result was compared to similar studies done within the country and outside the country and with the European Commission on radiological protection as seen in Table 6 and Figure 3. The ESD obtained in this study is much higher than those obtained in similar studies as well as the recommended Diagnostic Reference Levels (DRLs). The method adopted in the study was recommended by the international commission on radiological protection, as a result of this, comparisons were reliably made with the reference values and similar studies. The result has shown that entrance surface doses and radiation doses to the thyroid exceed the permissible value in Usmanu Danfodiyo University Teaching Hospital (UDUTH) Sokoto.

“…One of the fundamental quantities for calculating patient dose as well as for maximizing patient dose is ESD. ESD is commonly determined using any one of the following available methods: direct measurements using thermoluminescence dosimeters (TLDs), indirect method using mathematical formula based on the X-ray machine setting, or as simulation using phantom and software (Jornet N., 2013;Gaetano C., et al, 2005;Shabon M., 2014).…”

Concern regarding the radiation doses to patients exposed to x-ray during radiography examination has increased on a global scale. With chest x-ray radiography as the most common performed radiography examination, this study assessed the doses patients undergoing chest x-ray radiography are exposed to, through measurement of ESD (entrance surface dose) exposed at radiology department federal, medical center Katsina, using both direct and indirect methods for the purpose of diagnostic reference levels (DRL). Thermoluminescence (TLD) dosimeter is used for the direct measurements, while Tin and Tsai formula (mathematical equation) and CALDODE_X 5.0 software are used for the indirect measurements. The Entrance Surface Dose (ESD) was found to be; Tin and Tsai: 0.15 mGy (Chest AP), 0.12 mGy (Chest PA), 0.21 mGy (Chest lateral), with CALDODE_X: 0.23 mGy (Chest AP), 0.19 mGy (Chest PA), 0.31 mGy (Chest lateral), and TLD: 0.22 mGy (Chest AP), 0.20 mGy (Chest PA), 0.37 mGy (Chest lateral), and were all below the DRLs recommended by national and international regulatory authorities. The comparison of this study with other international and local reference levels shows that the LDRs from this study were lower than other international and local diagnostic reference levels for the three employed methods and for both projections.
