The spatial and temporal distribution of radionuclides in children may differ greatly from that accepted for adults. Following injection of a bone-seeking agent (/sup 99m/Tc-EHDP), radioactivity in the metaphyseal growth complexes of the distal femur and proximal tibia was quantitated in a series of children 4 to 16 years of age, using a gamma camera/computer system. The dose to the growth plate was found to range from 0.8 to 4.7 rads when adjusted to an administered activity of 200 ..mu..ci/kg, compared to approximately 0.6 rad to the adult skeleton for a corresponding study.
