This study aims to simulate the recent thyroidal kinetics data of 99mTc­pertechnetate from literature in a 3D-printed anatomically realistic thyroid phantom and to compare the resulting radiation dose with the ICRP publication and OLINDA/EXM software. \nA dynamic technique was applied by using an infusion pump via one infusion and drain pole connected the thyroid phantom to an auxiliary silicon-based hose. This is to simulate the biokinetics of influx and efflux of the 99mTc inside the thyroid gland. \nThe corrected accumulated activities of 99mTc-pertechnetate inside the thyroid from ICRP and the recent publication were applied, where two concentration 4 % and 7 % of the administered activity (370MBq) were used.\nThe radiation dose was measured inside each lobe of the 3D printed thyroid phantom using two sets of TLD and OSL dosimeters. The results compared with the calculated values from ICRP and the OLINDA/EXM internal dosimetry computer program in both concentrations.\nThe results showed slightly similar values from ICRP and the dosimeters results for the kinetics data of 7% concentration. Meanwhile, it showed a noticeable difference when the 4% kinetics data applied with a percentage difference of 28%. However, the results from OLINDA/EXM showed a significant difference when comparing with the ICRP and the mean dose of the dosimeters from both kinetics data applied. \nThe different values obtained from the practical measurements could refer to the biokinetics technique used and to the precise geometry size and shape of the 3D-printed thyroid phantom as well as the positions of the dosimeters inside the phantom. Therefore, this technique can be used to evaluate the absorbed dose as an alternative and practical method for an individualised dosimetric approach. This study suggests that the ICRP could take into account and include the most recent published studies, where it still refers to the publication and models published more than 40 years ago
