| Outline of Final Research Achievements |
Regarding stray radiation during intraoral radiography, the distribution of air kerma differed depending on the structure of each unit.The dose reached the maximum level in range at an angle of 0±15 degrees ahead of the useful beams, while the dose reached the minimum level in range at an angle of 180±15 degrees backward on the opposite side.
In the event of a large-scale disaster, operators would be taking many radiographs for victim identification in facilities without X-ray rooms. If an operator uses InSight film and takes about 100 radiographs per day. During a period of extensive victim identification work, a control area should be designated appropriately, the operator should control the unit from a vantage point of more than 2 m away from the radiation source, the operator should wear a lead apron (0.25 mm Pb eq.) and a protection board should be fixed. However, these protective measures are not always necessary if intraoral radiography is needed on a transient basis.
