| Abstract | From the Principle of Radiation Protection for workers, radiation shielding is a way to reduce radiation exposure. Thisstudy aimed to assess the efficacy of shielding device in reducing effective doses experienced by radiological technologistsworking in a PET/CT examination room by measuring the equivalent dose with and without shielding device in phantoms using18F 518 MBq at the National Cyclotron and PET Centre, Chulabhorn Hospital, Thailand. The phantoms were placed at theradiological technologistsโ working position and nanoDotTM OSL dosimeters were attached at eyes, thyroid, and chest positionsfor 30 minutes. The experimental results showed that the effective dose measured with and without the radiation shields were0.249 ยฑ 0.030 mSv and 0.250 ยฑ 0.020 mSv, respectively. Furthermore, data analysis revealed no statistically significantdifference (p >0.05) between the two conditions. Hence, it was concluded that the use of radiation shields could not reduce theeffective dose. |
