Determination of skin and bone dose in LOJ technique according to sex and age

The most convenient method for determining bone dose during extra-oral radiography is photographic radiation desimetry.This method was used because, it is cheap,small lightweight and adequately sensitive and it also provides a permanent records [10]. It is evident from this report that a relationship exists between the bone and skin dose, age and sex. In conclusion reduction of absorbed dose can be accomplished by changing the characters of the x-ray beam,its characters can be changed by reduction of,the beam diameter and increasing total filtration to 2.5 mm. of Al.[9]
