(CS 2400P) reduced 60% compared to the adults based on the literature.
National DRLs have been typically set at a rounded 75th percentile of the dose distribution.
The values presented in Table are proposed as new NDRLs for the UK.
X-ray type Patient size Proposed NDRL
Intra oral
Adult mandibular moral 1.2mGy
Child mandibular moral 0.7mGy
And We got the data using Portable Dental X-ray (CS 2400P). These exposed dose
values are more safer than requirements of NDRLs for the UK in adults and children.

• Strategy of reduction of X-ray for pediatric patients
According to the prior results the change over age and gender for Mandibular Angle
Breadth is 3% at maximum. And the BMI which related to body shape have change over
age and gender of 6% at maximum.
Therefore, we simplified the maximum change over gender, age, body shape as 6% and
we determined the range for exposure time.
In case of child, according to NDRL report*, the child to adult DAP ratio at 50th percentile
at mandibular molar intra-oral radiograph, panoramic radiograph, CBCT is 0.6, 0.7 and 0.6
