ISO FDIS 18310-1

Description / Abstract: This document specifies suitable methods for the measurement of ambient dose equivalent rate at a distance from the patient treated with radioiodine after thyroid ablation. For this purpose, direct measurement of the ambient dose equivalent rate to the inpatients using an ionization chamber (or other suitable devices) may be employed.

This document addresses the measurement methods, the calibration of ionization chamber and the uncertainty estimation for the measurement of the ambient dose equivalent rate of the patient treated with radioiodine after thyroid ablation using the ionization chamber.
