ResumoPurpose: The purpose of this research is to assess Kerma Area Product (KAP) to Effective dose (E) conversion coefficients (CC) specific to gender of patient and type of radiography technique applied during X-ray radiography of Chest. Methods and materials: A sample of 1723 adult and paediatric patient records examined on 81 X-ray systems was included in present study. Effective dose for each patient examination was assessed using Monte Carlo simulation software PCXMC, version 2.0.1. CC in µSv µGy−1 m−2 were determined using linear fit for “soft”—below 100 kV and “hard” radiography techniques with respective tube filtration for males and females respectively. Results: CC obtained for adult males and females were 1.14 (R2 = 0.93) and 1.25 (R2 = 0.97) respectively when using the “soft” techniques. For “hard” techniques CC values were 2.15 (R2 = 0.98) and 2.25 (R2 = 0.97) for males and females respectively. Conclusion: Present study shows technique and gender related differences in conversion coefficients estimated for standard adult patients. CC obtained for paediatric patients contribute to assessment of patient effective doses and hence the risk in individual and population exposures cases.
