Estimation of Pediatric Patient’s Radiation Dose During Nuclear Medicine Test

Abstract

Estimate of effective dose for pediatric in Khartoum state for three nuclear medicine scan the thyroid, Kidney (dynamic renal scan with DTPA) and bone using descriptive, analytic and cross sectional method in the research. the average of effective dose to all patients according to their age, for age group from 1-3 years old the mean for thyroid was 1.2 mSv, for dynamic renal scan 0.73 mSv and for bone scan it was 3.45 mSv. For age group 4-8 years old the mean for thyroid was 2.84 mSv, for dynamic renal scan 0.80 mSv and for bone scan it was 3.32 mSv. For age group 9-13 years old the mean for thyroid was 2.22 mSv, for dynamic renal scan 0.82 mSv and for bone scan it was 3.35 mSv. For age group 14-17 years old the mean for thyroid was 1.85 mSv, for dynamic renal scan 0.76 mSv and for bone scan it was 3.45 mSv. And the comparison between present study with other studies according to ED where for thyroid the present study was 2.03 mSv while in ARPANSA 2008 study it was 2.2 mSv which consider higher than our present study. For dynamic renal scan present study was 0.78 mSv while in ARPANSA 2008 study was 6 mSv which consider higher than our present study while in Silvia Maria 2014 study was 0.75 mSv which consider lower than our present study. For bone present study was 3.39 mSv while in ARPANSA 2008 study was 5.5 mSv which consider higher than our present study.
