In this study we assessed the efficacy of an automatic dispensing/injection system (ADIS) to reduce the radiation exposure of workers during PET procedures. NMW(Nuclear Medicine Workers) were classified into 2 groups, one of which used conventional method and the other used an ADIS. The radiation dose during injection were also measured in both groups, with another set of experiment. In dispensing step, ADIS imposed significantly less radiation dose than conventional method, both to finger and to whole body. In injection step, ADIS also imposed significantly less dose to finger, while the dose of whole body was somewhat larger in ADIS than in conventional method. Using ADIS, the radiation exposure of NMW during dispensing was markedly reduced. Also, the exposure of finger during injection was markedly reduced, although exposure of whole body was mildly increased.
