Conclusion and recommendations
The results obtained on the about 40 patients,
are in an age range between 0 and 15 years old and are grouped in the following sub-groups: 16 patients of 0 year old,
11 patients of 1 year old,
3 patients of 5 year old ,
3 patients of 10 year old,
4 patients of 15 year old.
Obviously the number of pediatric patients,
for this medical-radiological procedure,
is most frequently performed in a range-age of 0-1years.
The results show that the DAP values obtained are considerably lower than those recommended by PiDRL (Fig.3).
The effective dose values do not exceed 0.4 mSv for single patient,
even in cases where the duration of the examination has been long (Fig.5).
Regarding the dose to individual organs,
it is evident that as patients grow,
it tends to decrease,
especially for those not directly exposed to the beam.
In fact,
physiological growth causes an increase in the distance between the individual organs and the area affected by the radiation beam (Fig.4).
This study is important both from the dosimetric and the radioprotection point of view,
since on the one hand it allows to define an estimate of the dose detriment and on the other to respect the principles of radioprotection trying to optimize and reduce the dose values especially in relation to high radiosensitivity of the pediatric patients.
