ASSESSMENT OF OUT-OF-FIELD DOSES IN RADIOTHERAPY OF BRAIN
LESIONS IN CHILDREN, Int. J. Radiation Oncology Biol. Phys., Vol. -, No. -, pp. 1–7,
2010 To characterize the out-of-field doses in pediatric radiotherapy and to identify
simple methods by which out-of-field dose might be minimized, to reducing the risk of
secondary cancers Out-of-field doses to pediatric patients can be minimized by using
simple treatment

Pediatric organ and effective doses in dental cone beam computed tomography
Dental CBCT has been associated with higher radiation risk to the patients compared
to conventional dental X-Ray imaging. Several studies have investigated the radiation
doses involved in dental CBCT for adults, but none has looked into pediatric doses.
This study estimates the organ and effective doses to two pediatric tissue-equivalent
phantoms using thermoluminescent dosimeters for three dental CBCT units and six
imaging protocols. The doses to the thyroid, salivary glands and brain ranged from
0.068mSv to 1.131mSv, 0.708mSv to 2.009mSv and 0.031mSv to 1.584mSv
respectively. The skin and red bone marrow have received much lower doses than
the other three organs. The effective doses ranged from 0.022 mSv to 0.081 mSv.
The effective doses calculated in this study were much higher than these of
panoramic X-Ray imaging but lower than conventional CT

Radiation dose evaluation in the head and neck MDCT examinations with a 6-year-
old child anthropomorphic phantom, Pediatr Radiol (2010) 40:1206–1214 DOI
10.1007/s00247-009-1495-z
Background: CT examinations of the head and neck are the most commonly
performed CT studies in children, raising concern about radiation dose and their risks
to children.
Objective: The purpose of this study was to clarify radiation dose levels for children
of 6 years of age undergoing head and neck multi-detector CT (MDCT) examinations.
Materials and methods: Radiation doses were measured with small-sized silicon
photodiode dosimeters that were implanted at various tissue and organ positions
within a standard 6-year-old anthropomorphic phantom. Organ and effective doses of
