Description
Summary:In the present study, incident air kerma has been measured, for six intraoral examinations, for establishing regional adult diagnostic reference levels (DRLs), in intraoral radiography, in Tamil Nadu, India. A total of 131 units, both digital (semiconductor-based) and analog (film-based) radiography systems, were selected for the study. The third quartile values, for the six intraoral examinations selected for the present study, ranged from 1.2 to 2.0 mGy, for the adult settings. The results showed a wide range of patient doses existing across the clinics or hospitals studied. This is the primary study for the establishment of adult intraoral DRL, in Tamil Nadu, one of the major states of the country. Similar studies will be undertaken in other major states across the country to establish national DRLs in intraoral radiography in the country.
