In routine radiopharmaceutical Iodine-131 ({sup 131}I) dispensing, the amount of radiation dose received by the personnel depends on the distance between the personnel and the source, the time spent manipulating the source and the amount of shielding used to reduce the dose rate from the source. The novel iRAD-I131 dispenser using recycle {sup 131}I liquid lead pot will lead into low cost production, less maintenance and low dose received by the personnel that prepared the {sup 131}I. The new fabricated of low cost {sup 131}I dispenser was tested and the dose received by personnel were evaluated. The body of lead material is made from 2.5 cm lead shielded coated with epoxy paint to absorb the radiation dose up to 7.4 GBq of {sup 131} I. The lead pot was supported with two stainless steel rod. The Optically Stimulated Luminescence (OSL) nanodot was used in this study to measure the dose rate at both extremities for every personnel who prepared the {sup 131}I. Each OSL nanodot was attached at the fingertip. Three different personnel (experienced between one to ten years above in preparing the radiopharmaceuticals) were participated in this study. The average equivalent dose at right and left hand were 122.694 ± 121.637 µSv/GBq and 77.281 ± 62.146 µSv/GBq respectively. This study found that the dose exposure received using iRAD-I131 was less up to seven times compared to the conventional method. The comparison of experimental data using iRAD-I131 and established radiopharmaceutical dispenser was also discussed. The innovation of {sup 131}I dispenser is highly recommended in a small radiopharmaceutical facility with limited budget. The novel iRAD-I131 enables implementation of higher output liquid dispensing with low radiation dose to the personnel.
